NEMA FRAME CLUTCH-BRAKES Combination Air Applied Clutch and Spring Applied Brake Function: Starting and Stopping / Holding The Output Shaft Drive Arrangement: Motor to Gear Reducer (or Output Shaft Mounted Component) 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 Clutch Brake mounts between a c-face motor and gear reducer. or, Mounts to motor with a pulley or sprocket on the output shaft (see Detail Sheet for overhung load capacity). Clutch Brakes are designed for horizontal mounting. Consult engineering if vertical mounting is required. Applications Start/Stop, Cycling, Indexing. 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. Models listed have enclosed, aluminum housings. Clear anodized and stainless housing are also available. If needed, please contact engineering. Suitable for belt or chain drive (sprocket or pulley) applications.
