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.

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.

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.
