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.
Key Features of the Mach III custom design solution:
Torque Capacity: 2029 pound inches @ 50% spring compression
Totally enclosed, sealed, stainless steel construction
Bore Size: 1.0 Inch with Standard Keyway

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.

Mach III has solutions for connecting, disconnecting, stopping, holding, tension control and overload protection in food and beverage processing and packaging environments. We are experienced in adapting our clutch, brake and torque limiter designs with covers, seals and food safe components and lubricants. Finishes are available in stainless, electroless nickel plated steel and anodized aluminum. Learn more about some of the units we have produced for food and beverage handling applications.
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.
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 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.
- 82 Pound Inches Torque @ 80 PSI
- 5.13 Inch Outside Diameter
- 2.75 Inch Length
- 1.125 Inch Bore with Standard Keyway
- Aluminum Housing

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.
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:
- covered & made of food-safe materials
- end of shaft, flange mounting
- capable of handling the pulley belt load on the unsupported end
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.
