ADVANTAGES:
-
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 bearing 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 bush.
-
Electro plating is possible to prevent corrosion.
TYPICAL APPLICATIONS: PTFE-based self lubricating composite bearing TSB-10 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.
