SF-1 Carbon Steel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the Compound of PTFE and Lead as its surface. It offers the property of good self-lubrication, low wear, low friction good sliding characteristics, low noise. It has been widely applied to various mechanical sliding positions, such as textile machinery, printing machinery, hydraulic pressure transit vehicle, tobacco machinery, gymnastic instrument and agricultural machinery etc.

1.PTFE with lead 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm
1. Working under oilless or minim oil state, maintenance free or just need a little maintenance.
2. Resist Abrasion, low coefficient of friction long operating life.
3. Operating in -195℃～+280℃.
4. Good mending, low-noise, non-pollution.
5. Thin wall, light, which can reduce the machine to small.
6. Forming a transferred film during operation to protect shaft.
7. Low demand to the shaft even no surface hardness treatment, which lower the cost of the mating components.
8. No absorption to water/oil, small coefficient of Thermal emption, good thermal conductivity and size stability.
9. The back of the steel strip can be plated with various metal, anti-corrosion.
The products now are used in sliding components of different machines, such as auto machines, piston pump, gear pump, textile machine, auto-sides machine, Injection Machine, sports Machine office equipment etc.
