Automotive Rocker Arm Bimetal Bushing Steel Bronze Composite Sliding Bearing Sleeve

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.
