Self-lubricating bearings:
Structure:
Sliding layer ( PTFE )
Porous bronze sinter layer
Steel backing
Tin plated / copper coating
Characteristics:
It can be used where no oil can be applied or oil is difficult to be applied.
It has the advantage of low wear, low friction and with long life.
Low vibration, low noise and non-pollution in operation.
PTFE and lead film is transfered to the mating shaft to improve running properties.
The machine will be compact because of the thin thickness and low weight of the bush.
Application:
It is widely used in various sliding motions of different kind of machines, such as textile machine, tobacco machines, hydraulic vehicles automobiles, agriculture machines and so on.
