Oiles 81 - Oil-impregnated polyolefin bearings

The Oiles 81- Oil-impregnated polyolefin bearings series is available in multiple grades and is designed as self-lubricating bearings. This bearing is made of polyolefin with lubricating oil and unique filler which are distributed uniformly in plastic.

Features

  • The Oiles 81 bearing has superior wear resistance in abrasive conditions due to external foreign matter, rusting and coarse surfaces of mating parts.
  • Due to its unique property serviceable without the need for lubrication
  • The Oiles 81 has good mass productivity and is able to make complicated shapes.
  • The Oiles 81 has a low coefficient of friction as a result of superior impact resistance performance.
