The structure of self-lubricating wear-resistant copper bushing is very simple, that is, punching holes in the copper bushing substrate, and then inlaid with solid lubricant in the holes. The characteristics of this kind of copper sleeve are self-lubricating and maintenance-free, wear-resistant, low noise, high strength, long service life. It is mainly used for low speed, high load bearing occasions. Its material composition is generally high force brass (ZCuZn25Al6Fe3Mn3), can also be used tin bronze 555, tin bronze 10-1
Processing cycle is generally 5-15 days, the unit price according to the specific material, product specification size, the number of decisions.
Structure: By the high-strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4, SAE430B, HBsC4) as the base material, according to the use of the working conditions according to a certain proportion of the holes processed in the working surface and filled with solid lubricants, high-strength copper alloys to provide a very high load-bearing capacity and the solid lubricants can be formed to a lower friction vice.
Performance: Under dry friction conditions we design a pre-lubricated film on the bearing surface to ensure that the solid lubricant is transferred to the counterpart in the shortest possible time and an effective solid lubricant film is formed.
