The locking sleeve is a common component used for positioning bearings with tapered holes on cylindrical shafts, consisting of tightening bushings, locking nuts, locking washers and other parts, as this sleeve can be used on light shafts or stepped shafts, the sleeve is easy to install and does not need to be additionally fixed on the shaft. When using the locking sleeve on a light shaft, the bearing can be positioned anywhere on the shaft. When used with a stepped shaft in conjunction with a stepped ring, the bearing can be axially positioned precisely and the bearing can be easily withdrawn.

The locking sleeve is used to fix the tapered hole spherical bearing on the shaft without shoulder, simple structure, reliable work, convenient bearing exchange, widely used in textile, light industry, paper making, metallurgy, belt transport and conveying equipment and other industries.
