BEARPHITE CL

We developed "BEARPHITE CL" which is excellent in friction by precipitating the copper on the bearing surface with even small amount of copper with the development of the material and manufacturing method.

  • Even little quantity of copper combination, separating copper on the bearing surface secures friction abrasion characteristic.
  • Sliding performance :Same or better than bronze sintered bearings .
  • Durability:Same or better than conventional copper -iron materials.
Examples of use
  • Automotive electrical components: Power window motor, Blower fan motor
  • Information equipment Cooling fan motor
  • Office equipment: Photocopier Laser printer
