Characteristics
- Have incomparable performance under high load, low speed operation. Also perform well without lubrication
- Excellent wear resistance in places where an oil film is difficult to form due to reciprocating, oscillating motions and frequently intermittent operations
- Remarkable resistance to corrosion and chemical attack
- Maintenance free and saves 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.
