Model HSB Backstopping Clutch | Formsprag Clutch

HSB units are intended for use as backstops on the high speed shaft or intermediate shaft of reducers and as holdbacks on the headshaft of conveyors. They use standard FSO Series clutches with the addition of an oil reservoir made from an aluminum casting with cooling fins. HSB models are designed to permit free oil flow between clutch and reservoir to provide increased cooling capacity and increase backstop life.
