ZrO2/Si3N4/SSiC Double-Row Angular Contact Ball Bearings of 5200 series
Description of Ceramic Double-row Angular Contact Ball Bearings:
Because of the outstanding properties of ceramic materials, ceramic bearings have many kinds of performance advantages, such like 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.
