Overrunning clutch RIZELG2

Overrunning clutch bearing Feature

Type RIZ..ELG2 is a centrifugal lift off sprag type freewheel from Suma bearing oem when the inner race is overrunning. Only this race is designed for freewheeling. It is a self-contained
unit designed for overrunning clutch applications.

Typically used in crawl drives where the overrunning speed is high, but the Overrunning clutch bearing drive speed is low and does not exceed the maximum driving speed specified in the table. It is a type RIZ (» see page 84 for further information) equipped with an EL elastic coupling and a cover G2.

The EL type Overrunning clutch bearing is a high performance coupling used to damp torsional vibrations and to accept misalignment without excess bearing load.

The inner race must overrun and will be connected to the driven machine shaft. When ordered complete, the unit is delivered grease lubricated, ready for either horizontal or vertical installation. The torques given in the table are determined by the freewheel capacity.
