Mach III will modify its catalog model friction clutches, brakes and torque limiters or create an original design that connects to the shaft the way you prefer.  Pictured are a few examples, clockwise from top left:

• Traditional bore and keyway with set screw.  Available in both Imperial and Metric sizes with standard or non-standard keyways.
• Broached for a square shaft
• Extended hub with bore and keyway, slotted for connection to the shaft with clamp collar
• Extended hub with bore and shrink disc

Connect with Mach III engineering to discuss your application (again, whichever way you prefer):  US Toll free: 866-291-0849, International: +1 859-291-0849 or Email engineering@machiii.com.  All Mach III products are made in the USA and lead times for custom designs average only one week longer than for similar sized catalog products.

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.

Features:

• #3 Morse Taper Input
• Variable Output Options:  Unit shown has a 2.06 Inch square.  Other geometries available including imperial and metric bores with keyways.
• Maximum Torque Setting:  1400 pound inches

This air actuated friction clutch is a customized version of the Mach III C6D3K-STH.

• 7,405 lb.-in. Torque @ 80 PSI
• 2.125 Inch Bore with Standard Keyway
• Integral 6-5V Groove Pulley
• 0.25” NPT Rotary Air Union
• Enclosed Construction

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:

• Enclosed, sealed aluminum housing
• Grease packed under top oil seal and inside the flange housing to prevent water seepage
• Port in housing for vent tube.  Ventilation prevents the clutch from acting as a pump and drawing water into itself during disengagement.
• Custom output flange

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 . . .

• 208 pound inches torque @ 80 PSI
• 4.49 inches overall length
• 1.0 inch bore
• Double-single 60A19 sprockets
• Enclosed construction 

. . . and unlike a tooth clutch, it provides a soft start and can be engaged dynamically at higher speeds.

In the majority of the applications Mach III encounters our product connects to a round, keyed shaft. This application, however, connects two square shafts. Used on military equipment that is exposed to the elements, all of the metal components are stainless steel. The torque limiter portion (top photo) fits a 1.0 Inch Square, the coupling portion (bottom photo) 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.

If your design includes square or other atypical shafting, contact Mach III to explore a custom design solution. All Mach III products are made in the USA and lead times for custom designs average only one week longer than for similar sized catalog products.

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.  Contact Mach III with your special coupling requirements.

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.  For guidance on proper attachment of sprockets and pulleys, download our eBook:  Mounting Sprockets and Pulleys on Pilot Style Clutches

Mach III developed this covered brake, a variation of our SensiFlex® tension control brake, to provide tension on Mylar film during a coating process. There was a potential for overspray to occur so the brake needed to be covered. 

• 82 Pound Inches Torque @ 80 PSI
• 5.13 Inch Outside Diameter
• 2.75 Inch Length
• 1.125 Inch Bore with Standard Keyway
• Aluminum Housing 

The brake is pictured both with and without the cover.  Mach III makes a variety of covered clutches, brakes and torque limiters. Click below to see examples:
