[0002] A roll sleeve is a bearing part that bears important loads and rotational forces in mechanical equipment. A composite roll sleeve is usually composed of a combination of metal and other reinforcing materials (such as ceramics, polymers, etc.) to improve its strength, wear resistance and corrosion resistance. Roll sleeve composite centrifugal casting is a process method for manufacturing bearing parts, usually used for manufacturing bearing parts required in high-load and high-speed rotation applications. In this process, centrifugal casting technology is used to inject metal materials into a rotating mold to produce parts with the required shape.

The structure is simple and reasonably designed. The upper inner sleeve and the lower inner sleeve are not only convenient to replace, but also have good fixing effects. At the same time, it can adapt to upper inner sleeves and lower inner sleeves of different specifications, greatly reducing the production cost and having high practical value.
