Can self-lubricating copper sleeves replace bearings

The self-lubricating copper sleeve can replace the bearing in the case of low-speed and heavy-load movement. The self-lubricating copper sleeve is made of high-strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4, SAE430B, C86300) as the basic material. Holes are machined on the working surface and filled with solid lubricants. The high-strength copper alloy provides a high load-bearing capacity, while the solid lubricant can form a lower friction pair. Under dry friction conditions, we design a pre-lubrication film on the bearing surface to ensure that the solid lubricant is transferred to the mating part in the shortest time and an effective solid lubricating film is formed.


Therefore, the self-lubricating copper sleeve has self-lubricating properties and can also work without refueling, so in the case of low speed and heavy load, the self-lubricating copper sleeve can replace the bearing.
