PILOT INPUT CLUTCH-BRAKES TO STOP AND START THE SHAFT Combination Air Applied Clutch and Spring Applied Brake Function: Starting and Stopping / Holding The Shaft Drive Arrangement: Pilot Mounted Component to Shaft One air signal is required. Clutch torque transmitted is proportional to the amount of air pressure applied, brake torque is a fixed value. Operation Applying air pressure releases the spring applied friction brake and engages the friction clutch. Torque of the clutch is linear in response to air pressure applied above the brake release pressure. Brake torque is fixed by spring pressure. Mounting Through (Mid) Shaft or End of Shaft. Clutch Brake slides on shaft and is fixed with set screws and a customer supplied key. Anti-rotation arm required to react, brake, and prevent rotation of the air housing. Clutch Brakes are designed for horizontal mounting. If vertical mounting is required, consult engineering for options. Applications Stop/Start, Cycling, Indexing with input from a constantly driven sprocket or pulley. For applications with small brake torque requirement. Maximum RPM varies by model and is listed on the PDF detail sheet (see table below). Consult engineering if the intended application exceeds the listed maximum RPM. Design Features Clutch and brake combined in one unit for simplified mounting and control. Clutch brakes are bored to suit up to the maximum shown (US & Metric) for easy installation. Machined pilot for easy mounting of pulley or sprocket.
