Brass Oiles Self Lubricating Bronze Bearing



JDB-10S Special High Strength Brass Oiles Bronze Graphite Self Lubricating Bearing



JDB-10S graphite plugged oilless bronze bearing is made of centifugal casting special high strength brass with graphite filled. The hardness of base material can be more than HB250.This type of self-lubricating bearing is also called #500 oilless bearing,brass oiles bearing,cooper sliding bushing,solid lubricant filled sliding bearing,500 oilless guide bushing and graphite filled bearing.






PTFE or SL4 lubricant can be made based on requirement

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.
