PM Bearings - Ceramic Linear Bearings

Why ceramics? More than 2 decades of ongoing research and testing prove that ceramic linear bearings:
  • Maintain longer, more reliable performance;
  • Reduce friction;
  • Retain stiffness;
  • Operate at higher temperatures; and
  • Require less lubrication.
Through the years ceramic bearings have been well accepted in demanding ball bearing applications. As shown in table 1, ceramics are superior to steel in density and hardness. Cause of their non-magnetic property they are an ideal material for use in non-magnetic or ultra-high vacuum environment as in new generation machines.

Today, PM is the first linear bearing company in the world to realise practical use of ceramic linear bearings from diverse materials in our high precision positioning stages operating under extreme environments.
