Oiles Toughmet - Solid-lubricant-dispersed sintered bearings with back metals

The Oiles Toughmet series consists of two layers: sintered copper alloy layers with a unique solid lubricant spread uniformly and finely, and back metals for high-temperature and high-load applications.


  • Has exceptional load and heat resistance. Conductive as well.
  • If lubricating oil is used, the action of the sintered copper alloy layer's oil retaining power and solid lubricant produces far superior results.
  • conductive to electricity
  • The standard products come in a variety of sizes.
  • The thin bearing allows for a more compact design.
  • Superior performance is demonstrated even in reciprocating, oscillating, and intermittent operations.
