1. POM 0.03-0.50mm, anti abrasion,
low friction coefficient even no oil
given. The inside of the bearing are full of indentions, 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.
