Poliamide resin bearing with high rigidity under abrasive circumstance
|
|
 |
OILES 83 is a self-lub polyamide resin bearing containing lubricant and special filler.
|
| Features |
 |
Remarkable resistance to abrasion and heat without lubrication |
|
Grade using inorganic fiber retains high rigidity, outstanding impact load carrying capacity, and low in coefficient of liner expansio |
|
Retainable of stable performance with excellent wear resistance even under abrasive circumstances where foreign matters are encountered, the mating material is forming rust, or the surface of mating material is rough |
|
Injection molding enables complex shape. Suitable for mass production |
