A double acting piston drives the single clutch/brake disk against a driving plate for clutching, or against the
stationary braking surface for stopping. All friction surfaces are cooled by air drawn through the unit by an internal fan.
Size:
Approximately 7 inches in height, width and length, plus shaft extensions. The input and output shafts are each 1 inch in diameter.
Clutch and Brake Torque:
1,000 lb. in. at 100
psi. Torque is proportional to air pressure.
The following table shows maximum air pressure for a 5 year (10,000 hour) average thrust bearing life. We recommend that you reduce the theoretical torques and horsepowers in the table by a reasonable factor of safety, to allow for manufacturing variations in the coefficient of friction of our clutch and brake materials.

For maximum bearing life use only enough air pressure to adequately carry your load.
