“Rustproof and Human-friendly” Pure titanium bearings for various special environments
PDF Catalog Downlord↓


  1. Corrosion resistance usable in severer corrosive environment than AISI 304 stainless bearing, by using high corrosion resistant pure titanium class 2 for outer and inner rings
  2. Human-friendly without allergen reactions, as usable as in artificial joints.
  3. Non-magnetic bearing made of pure titanium rings and ceramic balls. By using ceramic balls allow insulation as well.
  4. Usable in low temperature environment by good low temperature toughness.
  5. Lower specific gravity: pure titanium 4.5 < SAE52100 7.8
