Product Description

 

Si3N4/ZrO2/SSiC Miniature Deep Groove Balls Bearings Of 630 Series Model

 

Why choose us:

 

At present, our company has abilities to produce fast all models of ceramic miniature ceramic bearings in material of  silicon nitride, zirconium oxide or silicon carbide. Ceramic Bearing are anti strong acid, strong alkali,salt and other corrosive media erosion, high temperature resistance, wear resistance, light structure, high speed limit, low noise, electricity insulation, the dimension keep stable under high temperature, smaller startup torque, keep working under bad lubricant condition, having longer using lifespan, and common metal incomparable advantages. Our company has our own material recipe and abundant production experiences, welcome your inquiry.
