Application characteristics

1、  It may be used where no oil can be applied or oil is difficult to be applied.

2、It has the advantage of low wear,low friction and with long life.

3、  Load will spread over a wider area due to the bearing material's elastic nature.

4、  Low stick slip properties ensuring accuracy of machine operation under low silding speeds.

5、Low vibration,low noise and non-pollution in operation.

6、  PTFE and Lead film is transferred to the mating shaft to improve running properties.

7、  It can be used in low hardness of mating shaft,so the shafts processing is easy.

8、The machine will be compact because of the thin thickness and low weight of the bush.

9、  Electro plating is plssible to prevent corrosion.It is widely used in various sliding motions of defferent kind of machines such as textile machine,tobacco machines,hydraulic vehicles Automobiles,agriculture machines and so on.

Provide standardized products:Cylindrical bushes P3、P7,flanged bushes P5、P9,thrust washers P6、P10,flat strip materila P6.

  Provide non-standardized products:Cylindrical bushes,flanged bushes,thrust washers,flat strip material,half bearing, wear plate,SF-10 with steel bush.
