FR151/DDR15X
This material consists of a copper-tin-lead alloy sintered onto a steel backing, and the bearing surface is a mixture of polytetrafluoroethylene resin (PTFE), lead/tin and a special filler. The bearing exhibits excellent durability under boundary and fluid lubrication conditions and has good sliding characteristics due to the PTFE/lead/tin mixture, special filler, strength of the metal material and dimensional stability.
