CHARACTERISTICS

◆  Can be used where no oil can be applied or oil is difficult to be applied.

◆  Low wear, low friction and with long life. Load will spread over a wider area due to the washer material’s elastic nature.

◆  Low stick slip properties ensuring accuracy of machine operation under low sliding speeds.

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

◆  PTFE and Lead filler is transferred to the mating shaft to improve running properties.

◆  Can be used in low hardness of mating shaft, so the shafts processing is easy.

◆  The machine will be compact because of the thin thickness and low weight of the washer.

◆  Electro plating is possible to prevent corrosion.


TYPICAL APPLICATIONS:

PTFE coated thrust washers is widely applied in various sliding motions of different kind of machines, such as textile machines, tobacco machines, hydraulic vehicles, automobiles, agricultural machines and so on.
