1.Working under oilless or minim oil state 2.With good quality and pretty competitive price 3.Standard or Non-standard is ok
Application character
1) Resist Abrasion, low coefficient of friction long operating life. 2) Operating in -195~+280 3) Good mending, low-noise, non-pollution 4) Thin wall, light, which can reduce the cubage of the machine. 5) Forming a transferred film during operation to protect shaft 6) Low demand to the shaft even no surface hardness treatment, which lower the cost of the mating components. 7) No absorption to water/oil, small coefficient of Thermal expansion, good thermal conductivity and size stability. 8) The back of the steel strip can be plated with various metal, anti-corrosion. The products now are used in sliding components of different machinery, such as auto machinery, piston pump, gear pump, textile machine, auto-sides machine, injection machine, sports machine, office equipments etc.
Material structure
1) PTFE/Pb Composition, 0.01~0.03mm, anti-abrasion material, which will form a lubricating film during operation. 2) Bronze powder layer, 0.2~0.35mm, which further strengther the combination of the steel plate and PTFE layer and transfer the heat more quickly. 3) Low carbon steel, bear high load and transfer heat. 4) Copper/Tin plating layer, anti-corrosion.
