One-way bearingsZYS One Way Bearings are divided into open type and sealed type. The keyway can be machined on the inner ring and outer ring.ZYS freewheel clutch is mainly used in such applications as speed conversion,Website:://.zys-bearing.com, reversal preventing, intermittent movement and etc. Working principle is to use friction generated by wedge, spring and such compression elements to transmit torque. Features: small size, transmitting high torque, smooth combining, high slip combining, working without noise, etc.Technical parameters of ZYS one way clutches:Fitted outer raceway diameter: φ30mm～φ150mmFitted inner raceway diameter: φ10mm～φ120mmMinimum mounting width: 15mm～30mmRated torque: 60N.m～4000N.mZYS freewheel clutches are mainly applied in aero-engine, reducer, starting system and the transmitting system of helicopter. Working speed can reach 30000rpm, and even 45000rpm in special condition.
