XY Assembly bearing



Introduction to materials

The product of steel back for the matrix, the middle layer sintering ball bronze powder, surface rolling modified POM (POM) and a storage pit, it has good wear resistance, in the less oil or gap off the oil conditions Can work properly, carrying pressure. It is suitable for swinging, low speed reloading, frequent opening and closing and loading start, etc. It is not suitable to form oil film. It can replace the traditional copper sleeve, reduce the cost and prolong the service life. It is widely used in forging machine, metallurgical and mining machinery, , Engineering machinery, rolling industry and so on.
