graphite plugged bronze bushing

Bearing Design – Shapes and Geometries

Double-cut Edge Center Flanged

  • Excellent resistance against cheemical attacks and low friction

  • Meet the maintenance-free as well as self-lubricated at long-term operating
  • Suitable for the tradition lubdcation cannot given or prohibited occasion, or in special conditions such as dust, radiation, impact Ioad but required the use of long-term and stability.

Consist of highly wear-resistance copper cast alloy whose sliding surfaces are evenly provided with a certain percentage of solid lubricant plugs according to work condition, high-strength copper alloy provides a high load-bearing capacity and the solid lubricant can be the formation of low friction Under technical dry running conditions. The bearing surface is designed with a thick running-in film which enables the solid lubricant to be transferred to the counter material at the first contact.
