5300 Series Ceramic Double-Row Angular Contact Ball Bearings Of ZrO2/Si3N4/SSiC
Performance advantages of ceramic bearings:
Ceramic Bearings have many advantages, like 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. So they are widely used in
aviation, aerospace, marine, petroleum, chemical, machine tools,
automobiles, locomotives, metallurgy, electronics, textiles, pumps,
medical equipment, food machinery, pharmaceuticals and other
fields.
