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.
