Description

Type RSCI is a centrifugal lift off sprag type freewheel with the inner race rotating. Only the inner race is designed for freewheeling.

Bearings must be provided to ensure concentricity of the inner and outer races and support axial and radial loads, as shown on the application example.

The RSCI type accepts all types of lubricants currently used in power transmission equipment. It is possible to mount these freewheels directly in gear-boxes without separate lubrication.

Run-out and squareness limits must be observed.

Primarily designed as a backstop, this type can be also used as an overrunning clutch in crawl drives, where the overrunning speed is high but the driving speed is low and does not exceed the maximum driving speed shown in the table.

When used as a backstop, it must be checked that the overrunning speed will not go below the minimum speed given in the characteristics table.

An oil mist is generally sufficient. Grease lubrication may be acceptable if the unit works mostly in overrunning condition, as on E-motors.

Centering of the outer race must use the inner bore. The centering spigot must not contact the sprag cage.
