  • Due to the effect of friction heat, the solid lubrication material in the aluminum brass groove on the inner diameter surface will expand slightly, which will produce a friction with the shaft in the first place and form a transfer membrane on the shaft, so as to reduce the friction coef., reduce the wear of the shaft and shaft sleeve, prolong the service lifeEspecially suitable for reciprocating linear motion conditions





  • Cylindrical oiles bushing, flanged oiles bushing
  • Special designs and material can be made according to your design.





JDB-60 bronze with with solid lubricant rings oiles bearing  is widely used in Guide bushings of precision molds,Precision guide rails.

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.
