1. Working under oiles or limited oil conbition, maintenance free or just need a little maintenance.

2. Abrasion  resistant, a low coeffcient of friction, a long operating life span.

3. Operating in -195℃~+280℃.

4. Good running-in property, low-noise, non-pollution.

5. Thin-wall structure, light in weight, which can reduce the mechanical sizes in designation.

6. Forming a transferred film during operation to protect shaft and trouble free.

7. Low demand to the shaft even without treatment on surface hardness, which decreases the cost of the mating components.

8. No absorption to water/oil, small coefficient of thermal expansion, good thermal conductivity  and size stability.

9. The back of the steel strip can be plated with various metals, anti-corrosion.

The products have been used in sliding areas of different machines, such as auto machines, pistons pumps, gear pumps, textile machines, auto-sides machines, Injection Machines, sports machines, Office equipments etc.
