  • A lead-free polymer fibre mixture provides an initial transfer film which effectively coats the mating surface of the bearing assembly, forming an oxide-type solid lubricant film

  • Sintered bronze powder provides maximum thermal conductivity away from the bearing surface and also serves as a reservoir for the PTFE mixture

  • Steel backing provides the high load carrying capacity which provides the wrapped bearings with outstanding heat dissipation

  • The copper/tin plating provides excellent corrosion resistance

  • These are versatile and extremely durable wrapped bearings and can be used in many applications. .
