RCB-20 lubrication bearings the same as SF-2 series.

  1. 1.It can reduce vibration, noise, pollution and improve working conditions.
  2. 2.In the process of operation, it can form a transfer film and play a role in protecting the grinding shaft. The hardness requirement of grinding shaft is low, which reduces the machining difficulty of related parts.
  3. 3.Thin wall structure, light weight, can reduce the mechanical volume.
  4. 4.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.
    5.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.
    6.Low carbon steel, which improved, load capacity & thermal conductivity.
  5. 7.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.

We are supply dry bearings, self lubricating bearing, wrapped bronze bearing, bimetallic bushings, steel bronze bushings, graphite steel bearing, bronze bushings, graphite bushings and so on.
