Product Description
JDB-10 High Strength Brass Bronze Graphite Self-Lubricating Bearing
JDB-10 graphite plugged oilless bronze bearing is manufactured using centrifugal casting high strength brass with graphite filling. This self-lubricating bearing is also known as #500 oilless bearing, brass oilless bearing, C86300 copper alloy sliding bushing, SAE430B solid lubricant filled sliding bearing, and various other industry designations.
Material Composition
CuZn25Al6Fe3Mn3 + Graphite
PTFE or SL4 lubricant options available upon request
PTFE or SL4 lubricant options available upon request
Key Characteristics
- Cost-effective solution with higher crash strength compared to other bronze graphite bearings
- Solid lubricant transfers to shaft through frictional heat, creating optimal oil-powder lubrication conditions that protect shafts from wear while maintaining lubricant longevity
- Hardness rating twice that of standard bronze graphite bushings
Product Availability
- Standard fabrication includes cylindrical oilless bushings, flanged oilless bushings, thrust washers, and slide plates
- Custom designs and material specifications available according to customer requirements
