 |
OILES Toughmet is a bearing for high temperature high load applications consisting of a couple of layers; sintered copper alloy layer containing uniformly dispersed special solid lubricant and steel back.
|
| Features |
 |
High load high temperature durability with electric conductivity |
|
Superb bearing performances even in cases of reciprocating and oscillating motions and intermittent operation |
|
Further improved bearing performance with oil based on dual functions of oil being adequately reserved by the sintered copper alloy layer and the solid lubricant contained therein |
|
Capable of compact design due to thin wall |
|
Available of a special model, OILES Toughmet L, with stainless back |
