Formsprag Clutch®
HSB-750 / 2.937

HSB (High Speed Backstops) units are intended for use as backstops on the high speed shaft or intermediate shaft of a reducer and as holdbacks on the head shaft of conveyors. They use standard clutches with the addition of the oil reservoir. The oil reservoir is an aluminum casting with cooling fins. HSB models have a spacer replacing the seal at the reservoir end to permit free oil flow between clutch and reservoir. The reservoir has a flush oil sight gauge and a filtered breather.
