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 polyetheretherketone resin (PEEK) and a special filler. It exhibits excellent wear resistance and durability under boundary and fluid lubrication conditions, and has good sliding characteristics due to PEEK, the special filler, strength of the metal material and dimensional stability.
