A double acting piston drives the single clutch / brake disk against a driving plate for clutching, or against the
brake drum for stopping. All friction surfaces are cooled by air drawn through the unit by an internal fan.
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.
This is an air actuated, air cooled, combination
clutch and brake for general industrial
applications. It is designed to be used for
any manual, cam or electrically actuated 1/4 inch
Always keep the fan guard in place.
For maximum bearing life use only enough air
pressure to adequately carry your load.
Do not use this unit with inertial loads greater
than 250,000 in.lb.energy.
Do not pick up loads at a rate greater than
2,500 in.lb. per second.
Avoid rigid couplings. Flexible couplings
allow for expansion and imperfect alignment and
help prevent serious bearing loss.
This unit is not designed for continuous slip
This unit should not be used in an explosive
Avoid locating the unit where friction surfaces
may be contaminated by oil or water.
All castings are heat treated ductile iron.
Bearings are well spaced and permanently lubricated.
The single pair of splines are more than two inches
long. The bonded friction linings are
The following table shows maximum air pressure for a 5 year (10,000 hour) average thrust bearing life
for various speeds with unit in the clutching
position. The bearing fatique is negligible
when unit is braking.
If this unit is operated at half the recommended
pressures and torques, the average theoretical
thrust bearing life will be 40 years because the
life of a ball bearing is roughly inversely
proportional to the cube of the applied load.
