Used for installing switching mechanisms on railway lines, the drill press to which this torque limiting coupling is attached sinks large screws into railroad ties made of various materials such as steel, concrete, plastic and wood. Each material requires a different size of screw and a different amount of drive torque. The railroad workers are able to manually adjust the slip torque setting of the coupling to the value needed for each material by loosening or tightening the adjustment nut. The output shaft allows for the quick interchange of sockets to accommodate the various screw sizes.
Mach III provides rapid turn-around for application adapted designs. This torque limiter was designed and quoted within 24 hours of the initial discussion between the client and our engineers. The units were manufactured within 3 weeks.

This holding brake is used to secure a load on a hoist until it is required to be moved, at which point air pressure is applied to release the brake. However, if the power fails and compressed air is unavilable, the user needed the option to manually release the brake and move the load by hand. Mach III engineers incorporated a lever that releases the brake manually when pushed in either direction.

A manufacturer of thermoforming machines needed a holding brake. They wanted to continue to use a servo motor made in Japan and a gear reducer made in the USA but no one offered a brake that could go between the different faces of the two components. Faced with either costly design changes or abandoning one of these trusted components, the OEM approached Mach III for a solution.
Mach III solved the dilemma with this spring applied, air released friction brake. The output side of the brake (top photo) has a 1.625 Inch Shaft with standard keyseat to connect to the USA-made imperial gear box. The input side (bottom photo) has a 55mm bore and features a locking collar which connects the brake to the Japanese metric motor.
This slip clutch was developed for an application where a food product is pulled through processing machinery by a wheel. Since there is a possibility of the food becoming jammed in the wheel, a torque limiter was need to protect the drive train that would be wash down compatible and meet food safety standards.

A food processing equipment manufacturer received an unexpected and unpleasant piece of news when they tried to purchase the nickel plated jaw tooth clutch they had designed into a new machine, a 16 week lead time! Needing a 5 week lead time to meet the delivery date required by their customer, the manufacturer contacted us. Did Mach III have a clutch that was equivalent? Could we deliver in 5 weeks? After reviewing the application and coordinating with production, our engineering team said, "Yes."
Our designers even found a way to expedite installation by incorporating an adapter so the clutch could be directly connected to the Lovejoy L150 elastomeric spider coupling used in the machine design.
The base for this design is the C5A2K-STH catalog model. For corrosion resistance, the unit is sealed and all exposed components are made from stainless steel and aluminum. This clutch is a prime example of the quick customization available from Mach III.

This spring engaged, air released friction brake was designed at the request of a thermoforming machinery manufacturer in Taiwan who needed to assure that a forming platen is held stationary in the absence of air pressure. Communicating by email across 7,800 miles and 12 time zones, Mach III’s engineers were able to obtain all the details about the application as well as the dimensions of the servo motor and gearbox the brake would go between.
Within a couple of days a design and quotation were presented for this holding brake which has 2,409 pound inches of torque. The brake connects directly to a Yaskawa SGMGV-IE 15kw servo motor on the input side and a Lenze GKS-11 3W gearbox on the output side.
Used on to raise and lower an antena on a military vehicle, this torque limiter coupling is exposed to the elements. Stainless Steel contruction assures that it up under the harsh conditions. The torque limiter portion fits a 1.0 Inch Square, the coupling portion fits a 0.75 Inch Square. The torque limiter protects the driven shaft by slipping if the factory torque setting of 1,800 pound inches is exceeded while the antena is raised.

This mechanical friction torque limiter was created in response to a customer’s request for a slip clutch with a 3180 pound inch setting and a 44L100 pilot mounted pulley. The first challenge of this application was that the outside diameter of the torque limiter could not exceed the diameter of the pulley. Mach III designed this unit with eight friction surfaces to deliver the required torque within the diameter restriction.
The second challenge was that the unit had to fit on a 1.25 Inch shaft. The design could accommodate a 1.25 inch bore, but there was no room for a keyway. Mach III extended the drive hub and fitted it with a locking collar to connect the torque limiter to the shaft.

Like many of Mach III’s custom designs, this brake design began with an inquiry about a catalog model spring engaged brake. An engineer working on a drive system needed a holding brake to prevent a Rexroth RAK-8D actuator from being back driven and losing position if air pressure was lost. The connection to the actuator was a 19mm square rather than a typical round shaft and key and, since the system would be on an offshore oil drilling platform, the brake had to be enclosed.
While it was possible to enclose the D4F3R-STH brake the engineer had inquired about and produce it with a square input, he would have to make changes to his design to connect the brake to the motor. Instead, Mach III engineers presented the concept of this enclosed spring engaged, air released brake with a flange containing six through holes on an 80mm bolt circle to connect directly to the actuator. The brake has 500 pound inches of torque and requires 77 PSI to release. The time span between the initial inquiry and the quotation for the custom design was just 4 days. The lead time to produce this completely custom brake solution was only 3 short weeks.

This torque limiter is used as a tension brake. The operator uses the knurled adjustment knob to vary the tension on a roll of film as it is unwound and applied to an architectural panel. The unit is constructed on a solid drive hub that extends from the unit and has a half inch wide and deep slot output to accommodate the tang on the core chuck.
Other configurations of this design are possible so if on-the-fly adjustment would be a benefit in your application, contact our factory based engineering and design team. All Mach III products are made in the USA and lead times for custom designs average less than 4 weeks.
This combination clutch-brake is similar to Mach III’s catalog model W4A2H-STH which has a ball bearing pilot on which a sprocket or pulley can be mounted. The pilot is driven when air is applied and held stationary when air is absent. An application called for the unit to have a 36 degree, 3L groove pulley with a 3.96 Inch pitch diameter which is too small to fit on the pilot. Mach III made modifications to reduce the size of the internal components so that the pulley could be incorporated directly into the sleeve.
What makes this Mach III brake custom? Not much, really. It is basically a catalog model D5C3R-21H spring applied brake with an output shaft diameter of 1.125 Inch instead of 1.375. A minor change, but when the brake must be mounted between a 213TC NEMA frame motor and a 182TC NEMA frame gear box it is a major difference. No longer does the client have to purchase a brake, disassemble it, turn down the output shaft and put it back together. This Mach III brake is out of the box and on the machine with a lead time of only 3 weeks.
This clutch is similar to the 58SI SensiFlex® shaft input tension control clutch. It has been modified to include a pilot mounted coupling hub which mates with a spider coupling (a.k.a. jaw coupling). This clutch is drop-in ready to simplify installation.
Would a custom design make your assembly process easier? Mach III supplies custom adapters and couplings for many catalog models.
This air actuated friction clutch is a customized version of the Mach III C6D3K-STH.

At Mach III, we try to find balance between due diligence regarding new applications and driving our customers and prospects crazy with questions, but this is one example of where it prevented a costly mistake. This design evolved from an order for the V6G1G-STL torque limiter mechanism with coupling. The catalog model was chosen by the end user after consulting Mach III’s website and the company tasked with building the equipment ordered what was specified.
At the time of the order, however, there were several red flags that led to contact between Mach III’s engineering team and the project engineer. Their discussions and a review of layout sketches revealed that V6G1G-STL was unsuitable as there was no support for the coupling shaft and the unit did not have the required torque capacity. The unit which resulted, V6G2G-001 pictured above, includes a rigid coupling with internal bearing to pilot the 1.75 Inch drive shaft and support the 2.0 inch coupling shaft. It has a torque capacity of 8,777 pound inches, almost 3 times more than the model originally chosen.
The application for this spring actuated holding brake required a minimum 3,300 lb-in torque capacity. Our engineers first recommended the Mach III catalog D8F3K-STH, however, the machine design could not accommodate the 11.75 inch flange diameter of this standard model.
To accomodate the radial space constriction, Mach III used the D6F3G-STH brake as a base and incorporated additional friction surfaces. The result was a brake with 4,405 pound inches of holding torque within a 9.53 inch diameter.
Mach III frequently adapts catalog products to meet the individual needs of the application. In this example the customer required a combination clutch-brake that would drive a pilot mounted sprocket when engaged and hold it stationary when disengaged. However, the environment in which the clutch-brake would operate was dusty and there was a potential for particulates to enter the clutch-brake where they could cause premature wear or failure.
Mach III adapted the cylinder portion of a catalog model W4A2H-STH clutch-brake by expanding the outer diameter and elongating it to form a cover. Both the catalog model and modified design are shown on the right.
This or a similar solution can also be used in clutch, brake and torque limiter designs.
Returned to Mach III for factory repair, the letters “JHG” were stamped in the housing of this multiple disc friction clutch which is used on an accumulating conveyor. Under Mach III’s former date coding standard, this means the clutch was manufactured in October, 1987 – 28 years ago!
Designed for use at low air pressure to minimize wear, this clutch provides 2,300 pound inches of torque at just 30PSI and includes integral 60A21 and 60B21 sprockets. Mach III also produces combination clutch-brakes with integral double-single sprockets for chain driven live roller conveyor applications requiring a controlled stop to prevent drift of product, pallets or containers.
Mach III’s catalog model NEMA Frame clutches have a female input bore and male output shaft and are designed for coupling motors and gearboxes. But what do you do when you need to couple two components with output shafts, one metric and one imperial? Insert a custom designed Mach III clutch with NEMA housing that has a female input on both sides.

An air engaged friction brake and air released coupling are combined in this custom designed assembly. The brake stops and holds a roll of material during a laminating process. When the process is complete, the user applies air to the coupling which then slides open. The roll, joined to the coupling with a tang-end shaft, can then be quickly removed.
The air released coupling is also available as a stand-alone item.
Mach III offers all-in-one, easy to install solutions to your clutch needs. One example is our ability to adapt our heavy duty end of shaft mount air engaged friction clutches to accommodate the exact v-belt pulley required by our customers. Clockwise from top left:

A pair of these clutches drive vertically mounted brushes which scrub the sides of a vehicle in an automatic car wash. This clutch had to fill two requirements: (1) operate in an environment where exposure to both water and detergent is constant and (2) support the brush assembly. Below are the special features incorporated into this design:
Mach III’s catalog model clutch-brakes require only one air signal to engage the clutch. Clutch torque is linear in relationship to air pressure applied. The brake engages automatically with spring pressure as soon as air is exhausted from the clutch at a fixed value.
Sometimes, however, a client requires more torque than can be provided with the catalog design. This custom model incorporates both an air set clutch and air set brake. The clutch and brake are controlled with separate air signals (see air inlets marked “B” for brake and “C” for clutch) and torque can be varied in both the clutch and brake portions of the assembly.

Developed as a retrofit replacement for a tooth clutch, this compact air actuated friction clutch provides . . .
. . . and unlike a tooth clutch, it provides a soft start and can be engaged dynamically at higher speeds.
This clutch is designed for use in a chain driven live roller conveyor.
This air released coupling was custom designed for an application requiring a quick and simple means of inserting and removing rolls of material. The face of the coupling (right) bolts to the machine frame. Air is applied to the coupling when the operator presses a button which retracts the sleeve and exposes the slotted shaft end. The operator can then slide a tanged shaft into the coupling. When the air is released, the coupling sleeve closes to retain the shaft.
The shaft is driven by a clutch which is connected to the extended shaft shown on the left side of the coupling. This coupling can be used with a clutch for stop/start or tensioning applications or a brake for stopping, holding or tensioning applications
For this low speed application, a Mach III end of shaft mounted clutch with a bronze bushing pilot was required. The pulley the customer intended to use, however, was too wide for the pilot of the catalog model clutch and would have resulted in an overhung load. Operating a clutch with an overhung load will cause uneven and premature wear and may result in the clutch “walking” off the shaft.
To accommodate the pulley, Mach III produced the pictured clutch which is similar to the catalog model only with an elongated pilot. The elongated pilot provides proper support for the pulley by centering it over the bronze bushing.

Mach III developed this covered brake, a variation of our SensiFlex® tension control brake, to provide light tension on Mylar film during a coating process. There was a potential for overspray to occur so the brake had to be protected. The brake is pictured both with and without the cover.

A departure from Mach III’s typical housing geometry and shaft mounted designs, these spring applied – air released puck brakes were developed for a manufacturer of web finishing and processing equipment.
So, if you did not see anything on this website that looks like what you need, it does not mean that Mach III cannot or has not manufactured it. To date, Mach III has designed and manufactured more than 2000 custom designs.
An arm used to position components during the assembly of an aircraft had problems with overload when it went into use. The arm was articulated by a timing belt pulley located at the pivot point that was driven by a belt connected to the motor. Extra load put on the wing assembly transferred backward through the arm to the motor. A torque limiter would resolve the issue, but there was only one inch of axial space available between the pulley and frame in which it could be placed.
Nothing existed that was that thin and would deliver the needed 530 pound inches of torque required. It appeared redesign and rebuilding of the arm might be the only option, one which would be both time consuming and costly.
Luckily, Mach III’s engineering team figured out how to combine the timing belt pulley and torque limiter into one component. Nothing had to be moved; even the belt position was maintained. Just as remarkable, Mach III expedited production to keep the maker of the assembly arm out of hot water with their client. Only 12 days after the application was presented to Mach III, 5 complete torque limiter/pulley assemblies arrived onsite.

Mach III offers a variety of catalog models for shaft-to-shaft coupling. Those catalog models provide shaft attachment with a keyway and set screw.
For this application, the customer wanted to attach the coupling half to the shaft using a keyless frictional locking device. Mach III outfitted a catalog model through shaft pilot mount clutch, C5A2R-STH, with a custom designed coupling.
Would a custom design make your assembly process easier? Mach III has custom adapters and couplings options for many catalog models.
For a laminating machine, the customer required Mach III’s catalog model 58PI SensiFlex tension control clutch. However, the machine design called for a 44 tooth, 5M belt pulley that was too small in diameter to fit on the clutch’s 2.75 inch diameter pilot. The solution to this dilemma is a custom adapter including a P44-5M-25 pulley that bolts to the 58PI pilot. The set screws which fix the clutch to the shaft are accessed through a hole in the adapter.
Mach III has the capability to supply custom adapters and couplings for many catalog models.
The brake pictured is designed for a machine that requires a slip brake to maintain tension on spool of transformer wire but has a very narrow envelope in which to accommodate it.
Mach III designs and manufactures clutches, brakes and torque limiters in custom c-face configurations. In this example, the customer needed a device to limit the torque between the motor and a coupling which was used to fasten a cap. The customer required the torque setting to be adjustable.
Mach III suggested an air engaged clutch. The customer would be able to adjust the torque applied to the capper coupling by increasing or decreasing the air pressure supplied to the clutch. When the capper met resistance, the clutch would slip.
Unique in this application was the motor face which required that the clutch mounting flanges be off-center from the clutch housing. The motor and capper coupling were sent to Mach III so the dimensions could be verified. The second photograph shows the finished clutch in place between the motor and capper coupling.
Mach III commonly modifies catalog products and designs entirely unique assemblies to match customer’s mounting requirements. In this example, Mach III’s customer sought an alternative for the electric combination clutch-brake shown on the right. The original unit was manufactured outside the US, was costly and had a unacceptably long lead time. After obtaining the application specs to determine the required clutch and brake torque, Mach III designed a drop-in replacement. Time to complete the application review, design process and production of the unit was just 5 weeks.

Friction clutches from Mach III Clutch, Inc. can be shipped complete with a pilot mounted sheave. In some cases, the sheave is manufactured by Mach III and fitted onto a catalog unit. In other cases, the length or diameter of the sheave may require modification of the unit to provide the proper support. Below are examples of each.
The customer who purchased this C8D3K-STH heavy duty, end of shaft mounted friction clutch required a 15 Inch O.D. 3-5V groove sheave on the pilot. Mach III manufactured both the clutch and sheave and shipped the complete assembly within four weeks.
The customer who purchased this unit needed something similar to the catalog model C6D3K-STH, but with a 7.0 Inch diameter, 4-5V groove sheave which was too long and too small a diameter to fit on the pilot of the standard model. Mach III modified the catalog design by lengthening the unit and making the sheave an integral component mounted on bearings directly on the drive hub.
In addition to providing the required sheave, Mach III offers every catalog product with a range of bore and keyway sizes so customers are not required to modify their shaft or use bushings to obtain the correct fit. Also shipped with a rotary air fitting, these clutches are both out-of-the-box ready for quick installation.

Having founded Caulder Converting (Hendersonville, NC) as a contract converting company, Dennis Caulder knew first hand the frustration of working with clutches and brakes that engaged at too high a pressure and then pulsed or cogged during operation. He sought to eliminate such problems when his company started manufacturing converting equipment of it’s own. While searching the web in 2007, he came across Mach III’s SensiFlex® tension control clutches and brakes. Interested by the fact that SensiFlex® was specifically designed for converting applications, he decided to try a 58PI clutch for a press that he was building. Since that time, Caulder Converting has used Mach III clutches and brakes on all of its presses. According to Dennis, “Nothing else compares for narrow web converting.”
Caulder Converting uses a component-type design allowing them to layout and build each press tailored to their customer’s needs. Their most recent project is the eleven anvil, seven inch press pictured here. Designed to produce a multi-layered medical device, this variable speed press runs from 40 to 50 feet per minute. The press incorporates a total of twenty two SensiFlex® clutches and brakes including the 58PI shown below.

If you’ve witnessed any type medical procedure or even had a simple blood test you have seen sterilized supplies and instruments removed from packages. These could be items as simple as bandages and swabs or as complex as surgical kits, drug coated stents or heart bypass valves. There are a variety of ways those items became sterile. One possibility is that they were processed through an Ethylene Oxide Sterilizer designed and manufactured by Getinge UK. In such a system, items are placed in a sterilization chamber after they are manufactured, packaged and palletized. Inside the chamber, ethylene oxide gas penetrates the paper or plastic packaging and chemically sterilizes the items.
Getinge engineer, Simon Butler, contacted Mach III Clutch, Inc. in search of a brake to hold the drive shaft in place on the automated shuttles that load and unload pallets into and out of the sterilization chamber. His working design called for a disc brake but due to design constraints on a specific project, he was seeking something more compact. After reviewing the application thoroughly with Mach III’s engineering department, a B3F2R-STH air engaged friction brake was selected. With a torque rating of 267 pound inches versus the 177 pound inches delivered by the disc brake, the B3F2R-STH provided an improvement in stopping time and holding capacity. When air is exhausted from the system, the Mach III brake also gives the user the ability to manually move the shuttle without causing any back drive against the motor which is useful during maintenance.
The Ethylene Oxide Sterilizer systems are manufactured in the United Kingdom. Since Mach III bores all catalogue products to customer specifications, B3F2R-STH brakes are shipped to Getinge finished with 20 mm H7 Class bores with 6 mm keyways. Systems using Mach III brakes are in operation in Finland and West Virginia. Two systems in progress are destined for Mexico and the UK. During a follow up to see how the brakes were performing, Simon Butler stated,
“As system designer I’ve been pleased with the performance of the brake - it’s compact size has also been a benefit to our system, allowing a greatly reduced overall system height.”
“As system designer I’ve been pleased with the performance of the brake - it’s compact size has also been a benefit to our system, allowing a greatly reduced overall system height.”

The Lights Camera Action attraction at Universal Studios Singapore provides visitors the experience of being on a film-production soundstage. The soundstage is set to simulate the scene from inside a waterfront boathouse in New York City during a category 5 hurricane. Visitors experience a scene filled with wind, rain, explosions, fire, and objects falling from the ceiling. Mach III clutches were used in the drive system that allowed elements of the scene (boats and steel girders) to free-fall into the water during the performance and then be quickly reset to their original positions before the arrival of the next visitors.
The elements which fall during the performance are suspended by cables. The cables are attached to winches that are driven by Mach III clutches. Spring engaged-air release clutches were selected based on the functional requirements. Since the clutches are spring applied, they remain engaged in the absence of air pressure. While a braking system assures that the winches are held in place, the engaged clutches provide redundancy. When the brake is released, air is simultaneously applied to the clutch to release it. The winch drums are then freed and the suspended element comes splashing down into the water.

A manufacturer of food packaging equipment contacted Mach III looking for a combination clutch brake which would stop and start a pinch roll shaft with constant input from an attached pulley. The clutch/brake had to meet the following special requirements:
The unit Mach III designed and manufactured was built from anodized aluminum, stainless steel and electroless nickel plated parts and food grade grease. To support the overhung belt load special bearings are used between the housing and drive hub. The clutch brake is attached to the machine frame using the tapped holes in the end plate. This combination air set clutch/air set brake is rated at 286 lb-in clutch and 143 lb-in brake at 80 PSI and is only 4-1/4” in diameter.
Mach III’s engineering department is available for assistance with selection of products for special environments.
A manufacturer of plastic thermoforming machinery needed a replacement for a troublesome caliper brake but no manufacturer offered a servo brake that would match the Japanese built servo drive (metric) and a U.S. made gear reducer (imperial). Mach III saved the OEM the expense of modifying the machine design by creating a c-face, spring applied brake to fit between the two components. This example has a 55 mm input bore and a 1.625 Inch output shaft. Torque rating: 6400 pound inches, 58 PSI release.

Mach III was contacted by a facility which uses large manually operated control valves. The quarter-turn valves are driven through right angle worm reducers by hand operated chain wheels. Due to the unfortunate fact that human beings are not equipped with torque sensors in their muscles, costly downtime failures were occurring when excess force was applied to the worm reducer via the chain wheel. Working with the facility's engineer, Mach III designed a special, keyless, friction torque limiter to connect the chain wheel to the reducer shaft.
In addition to designing and manufacturing the torque limiter, Mach III also provided the customer with a mounting diagram including suggested dimensions for machining their existing chain wheel to accept the new device. Although Mach III offers the service of machining existing mating components, in this case the customer's shop felt comfortable with the task. The torque limiter was successfully installed and adjusted to a setting where it would slip to protect the worm reducer when the shop gorilla swings on the chain.
Those accustomed to working with other clutch suppliers might assume that only an application promising considerable quantities would merit this level of attention. But this customer needed only three torque limiters, and spent just about one thousand dollars. So what is the motivation? A report from the customer that the new system "worked perfectly".
If you've got a nagging issue needing a clutch, brake or torque limiter solution and are concerned that no one will think it's worth their while, give Mach III a call. We know you will be pleasantly surprised.
The photograph below shows a pair of Conway 858 series clutch mechanisms used on a Norton Hyprolap lapping machine. Both units are mounted on a common shaft with one acting as a brake and the other as a clutch. Due to the design of the machine, diameter and length were very limited. To provide a drop-in replacement, Mach III created the M5R2K-001 clutch mechanism (link to drawing below) by combining the catalog-standard M5R2K-STH clutch mechanism with a custom designed adapter. The pair cost the owner of this machine less than $2,000.00 USD and saved the additional expense of machine modification.
Mach III has assisted a number of customers seeking items no longer available from Conway Clutch. While it is helpful to know the model number of the current Conway unit, it is more important to understand how the clutch is mounted and the function it is required to perform. Digital photos like those on the right or a sketch of the clutch and how it relates to the existing drive train are extremely useful. Contact Mach III for assistance replacing a Conway clutch or with any retrofit application.

This torque limiter is part of an assembly used to open and close a gate valve. The Morse taper input connects to a handheld power tool while the female square output connects to a square boss on the valve assembly. The torque limiter prevents over-tightening the valve.
