This is an environmentally friendly, lead-free bearing material. Copper-tin alloy is sintered onto a steel backing, and the bearing surface is a mixture of polytetrafluoroethylene (PTFE) and a special filler. Friction is very low and the bearing exhibits excellent durability under boundary and fluid lubrication conditions and has good sliding characteristics due to PTFE, the special filler, the strength of the metal material and dimensional stability.
