Cerbec® Silicon Nitride Balls

One of the world's most durable materials, silicon nitride is an ideal material for severe-duty applications where ball bearings are required:
  • Superior corrosion resistance – operates well in harsh chemicals, high heat, cryogenic, and other severe-duty environments.
  • Lightweight – Silicon nitride weighs less than half the weight of steel. This reduces force and wear.
  • Consistent surface finish – reduces wear and extends bearing life
  • Low density – Cerbec silicon nitride feature a density of 3.16 gm/cc
