Centrifugally Lift Off Sprags Freewheels RIZ G2G3 and RIZ G3G4

Types RIZ G2G3/G3G4 are centrifugal lift-off sprag type freewheels with the inner race rotating. Only the inner race is designed for freewheeling.

They are self-contained units designed for backstop applications. The overrunning speed must not be less than the minimum specified in the table. This must be considered if using a variable-speed drive. The torque bolt must be fitted into a slot on a fixed part of the machine. The radial clearance should be 1–3 % of the bolt diameter. The torque arm and bearings must not be axially loaded.

Type RIZ is equipped with G-type covers featuring grease pockets and contact-free seals. When ordered complete, the unit is delivered grease-lubricated, ready for either horizontal or vertical installation.
