Base Bronze Material Details

CuZn25Al6Fe3Mn3 Material Chemical Composition


  • Improves the hardness of brass base materail
  • Due to the high hardness and difficulty in processing, it is not recommended to use if the load is not particularly high.


  • Cylindrical oiles bushing, flanged oiles bushing, thrust washer and slide plate are standard fabrication.
  • Special designs and material can be made according to your design.


JDB-10S High strength bronze graphite oiles bearing is widely used in Continuous casting mill,Mining machinery,Engineering machinery,Injection molding machinery.

Mouting Suggestion

  • Housing – Ø: Mounting bevel, min. 1,5 mm x 15-45°

  • Shaft Material:Hardened steel, surface roughness < Rz 6,3

  • Shaft: Mounting bevel, 5 mm x 15°, edges rounded

  • Force fitting mandrel: The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.
