High Strength Brass Graphite Bronze Bearing Self Lubricating Bearing
JDB-10 High Strength Brass Bronze Graphite filled Self Lubricating Oilless Bearing
JDB-10 graphite plugged oilless bronze bearing is made of centrifugal casting high strength brass with graphite filled. This type of self-lubricating bearing is also called #500 oilless bearing, brass oiless bearing, C86300 copper alloy sliding bushing, SAE430B solid lubricant filled sliding bearing, 500 oilless guide bushing and graphite filled bearing, copper alloy oil free bushing.
Material
CuZn25Al6Fe3Mn3 + Graphite
PTFE or SL4 lubricant can be made based on requirement
Characteristics
- Cost effective and higher crash strength comparing with other bronze graphite bearings
- The solid lubricant of oiless bearing will run out to the shaft through frictional heat, forming an excellent condition for the coexistence of oil and powder lubrication, which not only protects the shaft from wear, but also makes the solid lubricant persist
- Hardness is twice higher than other bronze graphite bushings
Availability
- Cylindrical oiless bushing, flanged oiless bushing, thrust washer and slide plate are standard fabrication
- Special designs and material can be made according to your design
