Product Description

Type RSBI is a centrifugal lift off sprag type freewheel with the inner race rotating. Only the inner race is designed for freewheeling. It is a non selfsupported type. Including: RSBI60 RSBI70 RSBI80 RSBI90 RSBI100 RSBI130 RSBI150 RSBI180 RSBI190 RSBI220 RSBI240.

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.

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 caracteristics table.
