Lubrication-free

Resistant to dust and dirt

Small coefficient of friction

A mixture of modified polytetrafluoroethylene (PTFE) and lead (Pb) 0.01-0.03mm A wear-resistant material that can form a transfer film during operation to protect the counter-grinding shaft.

Copper powder layer, 0.20-0.3mm, improves the bonding strength of PTFE/Pb and copper plate layer, and has good bearing capacity and wear resistance. High thermal conductivity quickly transfers heat generated during operation.

Copper substrate 0.7~2.3, improve the bearing capacity and heat transfer of the bearing, and have better corrosion resistance
