Oiles 81 Oil-impregnated polyolefin bearings Feature Serviceable without the need for lubrication. Features low coefficient of friction and superior impact resistance performance. Demonstrates superior wear resistance in abrasive conditions due to foreign matter, coarse surfaces of mating parts, rust, etc. Injection-molded and can be made in complicated shapes. Has good mass productivity.
