Pneumatic disc clutch for web tension control
Mach III Clutch, Inc.

Design Features & Options
Tension control applications are unique. They require a clutch or brake that will operate smoothly throughout the entire converting process without the sticking, pulsing or cogging inherent in some designs. Heat caused by constant slip must be dissipated to prevent friction lining fade and premature unit failure. The clutch or brake must be capable of a broad range of torque output to supply the processing flexibility demanded from today's converting machinery.

Superior Heat Dissipation
The unique SensiFlex® design pulls cooler, ambient air into the pneumatic clutch or pneumatic brake then pushes it outward through radial holes to effectively dissipate the heat generated by constant slip. Higher thermal horsepower capacity is achieved without the addition of fans or expensive water cooling equipment. Lower operating temperatures reduce the chance of lining fade and increase the wear life of the unit.

Smooth, Low Maintenance Performance
Precision machining assures parallel alignment of the friction and drive surfaces for smooth operation and even wear. A single, specially molded, low coefficient friction disc provides smooth performance and exceptionally long life. All SensiFlex® pneumatic clutches have a dual bearing pilot which provides stability for a field or factory mounted sprocket or pulley, preventing deflection caused by belts or chains.
