Product Description
Product Overview
Our bimetallic bushing is manufactured by sintering copper alloy powder onto a low-carbon steel backing, forming a strong bi-metallic composite structure. The steel substrate delivers high mechanical strength and load-bearing capacity, while the inner sintered bronze layer provides outstanding wear resistance and low friction performance. Custom oil grooves and lubrication holes can be machined on the sliding surface to build stable lubrication film, ideal for heavy-load, continuous operation conditions in automotive, construction machinery, hydraulic and transmission systems.
Key Features
✅ Heavy load capacity & excellent impact resistance
✅ Low friction coefficient under oil/grease lubrication
✅ Good fatigue resistance and long service life
✅ Steel base for high rigidity; bronze sliding layer for tribological performance
✅ Customizable oil groove patterns, lubricating holes, dimensions
✅ Precision machined, tight dimensional tolerance
✅ ISO9001 certified, stable quality for mass production
