Hybrid Ceramic Ball Bearing of Steel Races+Ceramic Balls
Description of Hybrid Ceramic Ball Bearing:
Our company can volume produce all/hybrid ceramic bearings in steel or ceramic material and in C2/C3 or other customized clearance to meet your different demands. The races can be in material of stainless steel/ bearing steel or other steel you need and the balls can be in material of zirconia, silicon nitride and silicon carbide. The hybrid ceramic ball bearing combines the nice wear resistance of steel and the excellent resistance to corrosion and good electric and magnetic insulation of ceramic material.Hybrid ceramic ball bearings are low noise, non-locking at high speeds, resistant to dry friction, long life, cost effective and etc.
