Ceramic Bushing Bearing With Sleeve 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.

As a professional manufacturer of industrial ceramic components.We can custom the sepcial specifications of ceramic bushing bearing or other ceramic parts.

Ceramic bushing bearing is a kind of inorganic nonmetallic ceramic material made of natural or synthetic compound through forming and sintering at high temperature.It has high melting point, high hardness, high wear resistance, oxidation resistance and other advantages.

Best stiffness, highest hardness, high compressive strength, dimensional stability, electrical insulation, corrosion resistance
Delivery: 
Custom OEM will be shipped within 15 days after determining the parameters  
The samples will be shipped within 3 days
Quick Delivery Via Fedex,DHL,UPS,TNT Etc.
