What manufacture bearing bush?

Bearing bush  reduced with manufacturing of friction good sliding bearing materials, including metal material,such as copper alloy, aluminum alloy and Babbitt.And non metal materials ,such as plastics, graphite, rubber and wood.

  Some antifriction metal material strength is low ,such as Babbitt. Cast a layer only in the bearing surface of materials with higher strength,which called bearing lining. Support bearing lining part called bearing backing, used to be made by mild steel, cast iron or bronze.

  In order to further improve the bearing lining surface properties, plate a thin layer of metal  on the surface of reducing friction of the better ,such as indium.

  It is composed of different  multilayer metal material  called multi-layer metal bush. Bearing inner hole shape is basically not affected by the shape of the bearing seat hole called thick walled bearing.

  Inner hole shape depends mainly on the bearing seat hole shape called a thin wall bearing bush. Thin wall bearing is widely used in the machine of internal combustion engine, air compressor with mass production.
