Non lubricated bearings

Steel backed & Bronze powder with POM Marginal bearings,Lubricated Bearings

The sliding bearing specialist with in-house custom manufacture

Composite Cylindrical bushes

Metric Composite Plain bearing

sliding material, POM


Lead Free boundary lubrication bearing ROHS. It can be applied to the field where non-lead is required. Now its wldely used in textile machines,auto operating parts and other middle speed, middle load and grease lubrication occasions.

A Powerful Force: Self-Lubrication Bearing Bushing to Customers Around the World.

Material Structure

  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. Sintered 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 backing, which improved, load capacity & thermal conductivity.
  4. Copper/Tin plating layer, 0.002mm, anti-corrosion.
