1300 Series Ceramic Double-Row Self-Aligning Ball Bearings Si3N4/SSiC/ZrO2
Why choose us:
Our company can customize ceramic double-row self-aligning balls bearings of all kinds of models. The material of races and balls can be chosen among silicon nitride, silicon carbide and zirconia. The material of cage can be chosen among PEEK, and PFA, we can customize any material combination according to your requirement.
Material properties of ceramic material:
Ceramic Bearings 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.
