Backstop clutch bearing Feature
Type RSCI backstop clutch bearing is a centrifugal lift off sprag type freewheel with the inner race rotating from Suma bearing exporter. Only the inner race is designed for freewheeling. The backstop bearing is a non self- supported type.
Backstop Clutch Bearings must be provided to ensure concentricity of the inner and outer races and support axial and radial loads, as shown overleaf. Concentricity and run-out limits must be observed. The RSCI type accepts all types of lubricant currently used in power transmission equipment. backstop bearing is possible to mount these freewheels directly in gear-boxes without separate lubrication. An oil mist is generally sufficient. Grease lubrication may be acceptable if the unit works mostly in overrunning condition, as on E-motors.
When used as a backstop clutch bearing, it must be checked that the overrunning speed will not go below the minimum speed given in the caracteristics table.
