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.
