One-way thrust ball bearing
The unidirectional thrust ball bearing comprises an axle ring, a seat ring and a steel ball, a cage assembly. The unidirectional thrust ball bearings are separated, and the shaft ring, seat ring, and steel ball-retainer assembly can be installed separately.
The unidirectional thrust ball bearing can bear the unidirectional axial load and can make the unidirectional axial position, but must not bear any radial load.Customized Thrust Ball Bearing
