  1. PTFE / Pb composition, 0.01-0.03 mm, anti-abrasion material, which forms a lubrication film to protect the shaft during the machine in operation.
  2. bronze powder layer, 0.2-0.35 mm, which further strengthens the combination of the steel sheet and the PTFE layer. Bronze has good thermal conductivity. It can transfer the heat it produces
  3. during operation more quickly.
  4. Low-carbon steel, which improves load capacity and heat transfer.
  5. Copper / tin coating layer, anti-corrosion.



Oil-free or minimal oil condition, maintenance-free or fair need a little maintenance.
Resists abrasion, low coefficient of friction, long service life.
Operating in -190 ℃ ~ + 280 ℃.
Easy to mend, silent, non-polluting.
Thin, light wall, which can reduce the volume of the machine.
Formation of a film transferred during operation to protect the tree.
Low demand on the tree, even without surface hardness treatment, which reduces the cost of the coupling components.
No absorption to water/oil,small coefficient of thermal emption,good thermal conductivity and size stability.
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
