Product Description
High-Strength Brass Graphite Bronze Bearing
JDB-10 graphite plugged oilless bronze bearing manufactured using centrifugal casting CuZn25Al6Fe3Mn3 brass alloy with embedded graphite lubricant. This self-lubricating bearing delivers exceptional performance in demanding industrial applications.
Material Composition
Primary Material: CuZn25Al6Fe3Mn3 + Graphite
Alternative Lubricants: PTFE or SL4 available upon request
Product Characteristics
- Cost-effective solution with superior crash strength compared to standard bronze graphite bearings
- Self-lubricating mechanism: Solid lubricant transfers to shaft through frictional heat, creating optimal oil-powder lubrication interface that protects shafts from wear
- Enhanced hardness: Twice the hardness of conventional bronze graphite bushings
Product Availability
- Standard configurations: Cylindrical oilless bushings, flanged bushings, thrust washers, and slide plates
- Custom designs and material specifications available to meet specific application requirements
Industrial Applications
Metallurgical continuous casting machines, train supports, steel rolling equipment, mining machinery, gas turbines, and other heavy-duty industrial systems
