Specifications
  • Minimum Disengagement Pressure: 60 PSI
  • Maximum Operating Pressure: 80 PSI
  • Maximum RPM: 1,750
  • Bore Range with Standard Keyway: 0.313 to 0.500 inches
  • Air Volume (New): 0.14 cubic inches
  • Air Volume (Worn): 0.22 cubic inches
  • Finish: Aluminum
  • Construction: Open

Torque vs. Air Pressure
New clutch or brake torque is approximately 40% less than the rated design torque until the friction and drive discs are worn in. It is advised to use a service factor of 1.5 to 2 when calculating required torque and avoid using the product at its maximum rated torque for continuous duty.
Product Selection
Torque capacity is only one factor in product selection. It is recommended to contact the engineering department for application review and selection assistance.
Parts and Maintenance
Repair kits containing common wear items are available. Users should stock repair kits based on the number of units installed and the critical nature of the equipment. For pricing and lead time, contact customer service.
