OILES 470 is a bearing obtained by compression molding reinforced mixture of carbon fiber or cotton added with a special solid lubricant.

Features
ball Self-lubricating capability with low coefficient of friction and high resistance to wear especially in cases of underwater, in-chemical liquid and in-oil application
ball Retainable of stable performance with excellent wear resistance even under abrasive circumstances where soil, sand or other foreign matters are encountered or the mating material is forming rust
ball Available of multiplayer type (470-02W) consisting of 470-02 for sliding surface and 250 or 425 for packing material
ball Standard products of split metals and bearing units for flocculator available upon order
