introduction

Overrunning Clutch Bearing RSCI 180-300

Feature

    Type RSCI is a centrifugal lift off sprag type freewheel with the inner race rotating. Only the inner race is designed for freewheeling. 
    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. Centering of the outer race must use the inner bore.The centering spigot must not contact the sprag cage. Please refer to page 76 (RSCI 20-130) for further information.
