High Precision Technical Ceramic Bushing Bearings Made By Mingrui Ceramic

High Precision Technical Ceramic Bushing Bearings Made By Mingrui Ceramic
 
Ceramic bushing bearings are mainly composed of bushings (or bearing shells) made of advanced ceramic materials and shafts that match them. This type of bearing uses the high hardness, high wear resistance, high temperature resistance, corrosion resistance and other characteristics of advanced ceramic materials to improve the service life and performance of the bearing.

The Ceramic bushing bearing action Ring sleeve in the valve application field, bushing within the valve cover, generally uses the advanced ceramics and other corrosion-resistant materials, used for sealing effect. The bushings made of grinding bearings with abrasion-reducing materials are also called bearing bushings and bushings. Usually cast on the inner surface of the bearing, mainly in order to reduce costs, save valuable grinding materials. Thickness 0.5-6mm, for large size or important bearings. Ceramic bushing bearing  are mainly to replace the wear of the shaft, in addition to the support shaft operation, friction and wear reduction, vibration reduction role.
