These clutches are designed for backstop applications on the high speed shafts of motors, gearboxes, compressors and pumps. They can also be used within slow speed barring drive. Although basically these clutches require no lubrication, their sprag design does permit the use of E.E or H.P additives.
Type RSBI is dimensionally equivalent to many competitor units; type RBI offers higher torque capacity.
