Hybrid Ceramic Bearing 608 of Steel Races+Ceramic Balls
Description of Hybrid Ceramic Bearing 608:
Our company has an automatic assembly production line for 608 bearings, can volume produce 608 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 bearing 608 combines the nice wear resistance of steel and the excellent resistance to corrosion and to high temperature of ceramic material. They are non-magnetic, non-conductive, low noise, electrically insulated, non-locking at high speeds, resistant to dry friction, long life, cost effective and etc.
