OILES Drymet LF is a multi-layered self-lubricating bearing with tetrafluoroethylene resin filled overlayer, a sintered bronze interlayer and a steel backing.
|
| Features |
 |
Usable without lubrication. Thin-wall and lightweight construction for compact design |
|
Shows a low co-efficient of friction under at high load and low velocity condimon with excellent wear resistance |
|
Applicable to middle and high velocity at higher PV value, when lubricant oil is used together |
|
Usable under a wide temperature range and retain excellent resistance against almost any chemical attack |
|
Excellent dimensional stability, mechanical strength and thermal conductivity |
