C2H2R-STH Air Engaged Flexible Friction Clutch Coupling Important: Each shaft must be bearing supported. Engagement/Disengagement Air/Spring Facing Type High Coefficient Torque @ 80 PSI – Dynamic 190 Pound Inches Minimum Engagement Pressure 2.5 PSI Maximum Operating Pressure 80 PSI Maximum RPM 1,750 NEW vs. BURNISHED TORQUE New clutch or brake torque is approximately 40% less than rated design torque until the friction and drive discs are worn in (lapped, burnished). The length of time for wear-in to occur varies by application. Bore Range with Standard Keyway 0.313 (7) to 0.500 (12) Inches (mm) Air Volume New 0.10 Cubic Inches When calculating required torque always use a service factor of 1.5 to 2. It is not recommended to select a product for use at its maximum rated torque for continuous duty. PRODUCT SELECTION Torque capacity is only one factor to consider when making a product selection. Insure that you will have right product for the job by contacting our engineering department for application review and selection assistance.
