It all started with a small wooden bearing.


Solid-lubricant-dispersed sintered bearings with back metals

Bearings for high-temperature and high-load applications featuring superior foreign matter resistance

The Oiles TOUGHMET series are bearings for high-temperature and high-load applications composed of two layers: Sintered copper alloy layers where special solid lubricant is dispersed uniformly and finely, and back metals.

  • Has superior load resistance and heat resistance. Also conductive.
  • Demonstrates superior performance even in reciprocating, oscillating, and intermittent operations.
  • Demonstrates much superior performance by the action of oil retaining the strength of the sintered copper alloy layer and solid lubricant.
  • Thin bearing allows compact design.
  • The TOUGHMET L with stainless steel back metal is also available as a special grade.
