Overrunning Clutch With High Quality

We are offering overrunning clutch with high quality.
Types gfr, gfrn are roller type freewheels. These units are part of the stieber modular system. They are bearing supported, using two 160.series bearings, and require oil lubrication. These units may be used in designs providing oil lubrication and sealing as on the example overleaf. The bearings must not be axially stressed.
Typically, types gfr, gfrn are used with the f series covers that are designed to transmit torque, and provide oil lubrication and sealing. Usually these covers are used in pairs according to combinations shown on the following pages. The outer race of the gfr model is plain to receive and center any component bored to h7 tolerance.
Torque is transmitted by bolts through the cover plate in this case. Types gfr, gfrn are identical except that type gfrn has a keyway on the outside diameter to transmit the torque. Two paper seals are delivered with each unit to be placed between the outer race ad cover plates.
