2. The static and dynamic friction coefficient is similar, which can eliminate the crawling at low speed, so as to ensure the working accuracy of the machine. No oil lubrication or less oil lubrication, suitable for the places where it is impossible or difficult to add oil. It can be used without maintenance or less maintenance.
3. The transfer film can be formed in the running process of sliding bearing, which can protect the grinding shaft and avoid the phenomenon of shaft biting. The hardness requirement of the grinding shaft of sliding bearing is low, and the shaft without quenching and tempering treatment can be used, which reduces the processing difficulty of related parts.
4. Thin wall structure, light weight, can reduce the mechanical volume. The back of steel can be plated with various metals and can be used in corrosive medium. Sliding bearing has been widely used in sliding parts of various machines.
