Product Details

Ceramic Ball Bearing 689 699 609 629 639

Full ceramic bearing ZrO2 material has perfect propriety such like suitable for low and high temperatures, high load capacity, corrosion resistance, nonmagnetic insulated and self lubrication. Thus it suit for the specific applications which are not available for bearing steel and hybrid construction ceramic ball bearing materials.

Full ceramic bearing Si3N4 material has similar propriety as ZrO2 material, besides it has low weight , good wear resistance, high hardness, and it can bear higher temperature than ZrO2 material.
Full ceramic bearing Al2O3 material which uses 99% Al2O3 ceramic, its rolling parts are also using Al2O3 ceramic as well.
Compare with other 3 types of ceramic materials, full ceramic bearing SiC material is more outstanding in these aspects: higher chemical corrosion resistance, better strength, higher hardness, higher wear resistance, lower frictional properties, and suitable for the highest temperature.
