In-oil bearing with extremely low friction characteristics.
|
|
 |
OILES Lumet is an in-oil bearing composed of three layers; tetrafluoroethylene resin layer with special fillers, sintered bronze layer, and back metal. Developed exclusively for oil andboundary lubrication
|
| Features |
 Remarkable resistance to wear and loads in the oil or in the boundary lubrication
Strong resistance to cavitations in the oil or in the boundary lubrication
Operational in the wide temperature range
Thin-wall and light-weight for compact design
Outstanding strength and dimensional, rigiidity, mechanical
