Bi-metal Steel Backed Bronze PTFE/Fibre Bearing Bushing


Comparing with normal CSB-50, the thicker PTFE layer of this material is machinable after assembling to achieve a higher tolerance grade. At the same time, the thicker layer provides flexible torque range and a large range of clearance requirements for variaty of applications.

1.PTFE/Fibre mixture thickness 0.03-0.08mm. The PTFE layer is the contact surface for the rotating shaft . Minute particles of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
2.Sintered bronze layer thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3.Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying
and heat dissipation characteristics.
4.Plating,provides good corrosion resistance.
