    Product Description

  • Sintered metal, self-lubricating bearings are made from powdered metal alloys pressed and baked with heat to form various dimensions.
  • Upon exiting their moulds, the newly formed surfaces are formed with open pores. These pores channel lubricants between the bearing itself and the shaft.
  • The pores are then vacuum impregnated with an oil to improve the material's load bearing ability.
  • The bearing material holds approximately 20% oil by volume and acts as a "sponge like" resevoir.
  • The most common lubricant impregnated at the factory is straight SAE 30 oil.
  • Sintered metal is mostly made of copper with approximately 10% tin and up to 1% iron.
  • Sintered metals reduced coefficient of friction makes it useful for many applications.
  • Uniform oil coating of the mating shaft during operation ensures good lubricant distribution.
  • Due to the porous structure of sintered materials, machining them poses issues. A sharp cutting tool such as tungsten carbide is stipulated as it does not "smear" the surface of the sintered metal and block the pores lubrication ability such as a reamer will do.
