Self-Lubricating Bearing SF-1
The product is a copper plate as the substrate, the middle of sintered spherical bronze powder, surface rolling take tetrafluoroethylene (PTFE) and lead mixture, made of rolling bearing, similar foreign products into DU.
The product has a low coefficient of friction, wear and corrosion resistance and good lubricating characteristics. The use of the product can reduce costs, reduce machine size, to avoid the phenomenon of bite-axis and reduce mechanical noise and so on.
Now widely used for sliding parts of machinery, as printing presses, textile machines, the tobacco machines, fitness machines, hydraulic truck. Micro-motors, automobiles, motorcycles and agricultural and forestry machines and so on.

Note: Various materials are suitable for SF-1 Series products according to different working conditions ,such as bronze backing (SF-1B),stainless steel backing (SF-1S) and lead-free material (SF-1W)…
It may 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. 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 film is transferred to the mating shaft to improve running properties.
It can be used in low harness of mating shaft,so the shafts process-ing is easy.
The machine will be compact because of the thin thichness and low weight of the bush.
Electro plating is possible to prevent corrosion.
It is widely used in various sliding motions of different kind of machines such as textile machine , tobacco machines ,hydraulic vehicles Aotomobiles, agricul-ture machines and so on.
