OILES Cermet G is a self-lub bearing for high temperature use consisting of a sintered alloy and solid lubricant, main component of which is graphite, uniformly dispersed across the alloy structure.
|
| Features |
 Applicable in self-lub state with high thermal stability
No generation of cracking or crack growth at repeating exposure to high temperature
Superb performance when used at locations of high temperature where oil lubrication is hard to be applied
Available in material for machining
