Ceramic Ball Bearings

Ceramic Ball bearings (made of silicon nitride, zirconia oxide and alumina oxide) are kept in our stock series. They are advantageous in having a longer service life, lower friction resistance, higher seizure resistance, higher corrosion resistance, higher rigidity, higher temperature resistance ( up to 800C) lightweight (40% of bearing steel), non magnetic, and insulated. They can be used even in an extra high - vacuum environment.

Ceramic ball bearings for use in jigs, tools, gauges, solenoid valves, check valves, other types of valves, high-grade bicycle parts, automotive parts, machine components, etc.
