Shaft Mounted Clutches/Power-On Brakes - Type SLB and SOBShaft Mounted Clutches/Power-On Brakes – Type SLB and SOB

The SLB and SOB series are shaft-mounted Clutch/Power-On Brake packages that are used to couple two parallel or in line shafts.

The Clutch/Brake package combines the features of our model SL or SO with an FB into one unit for easy installation.

The clutch armature hub accommodates a pulley, gear, sprocket, etc., to transmit torque to the second shaft. The brake is used to stop or hold the load.

The Clutch/Brake package is shaft mounted and retained by a loose-fitting pin or bracket through the anti-rotation tab.
