1. POM 0.03-0.50mm, anti abrasion, low friction coefficient even no oil given. The inside of the bearing are full ofindentions, which need to be filled with grease before installing.
2.Bronze powder layer, 0.2-0.35mm, high load capacity and anti-abrasion, good thermal conductivity, which also further strengthen the combination of the POM layer and steel plate.
3. Low carbon steel, which improved,
load capacity & thermal conductivity.
4. Copper/Tin plating layer, 0.002mm,
anti-corrosion.

The product can be used under high load with low speed, rotation, oscillation, and also can be applied in no liquid lubricants environment that switches frequently with load; the part can work with out oil, and will have a long operating life if oil giver; the POM layer can be machined during installing, which does benefit to the mating.
The products now mainly used in metallurgy machine mine industry, irrigation machine, agriculture machine etc.
