Characteristics



● Have Incomparable performance under a high load, low speed operation. Also perform well without lubrication;

● Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations;

● Remarkable resistance to corrosion and resistance to chemical attack;

● Maintenance free and save operating cost


Availability




● Cylindrical oiles bushing, flanged oilless bush, thrust washer and slide plate are standard fabrication.

● Special designed solid metal bearing and material can be made according to your design.

● Other material can be made based on your requirement.


Application



JDB-50 Graphite plugged tin bronze oiles bearing is widely used in successive casting machine, mineral mountain machinery, shipping, steam turbine etc.

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.
