Update import bearing analyze the key points

We are in the process of using the imported bearing, often live to stop some die maintenance, but a lot of conditions, imported bearing is upgrading needs to stop, that is to say stop to change the bearing demand, old bearing with new bearings. China bearing network on the basis of understanding, notice everyone in the process of using the imported bearing, what time will need to stop to change the new bearing? Mainly from the following points can see: 1, imported bearing inner ring and outer ring, rolling body, insist on shelf have crack or gap on any one; 2, imported bearing raceway surface, guard, with significant roller card injury; 3, the persistence of the imported bearing wear, or rivet significant relaxation; 4, imported bearing ring, rolling body on any fracture; 5, imported bearing raceway surface, rolling body has serious indentation and mark; 6, imported bearing inner ring diameter or outer diameter surface has obvious creep; 7, imported bearing raceway surface, there are rust on rolling element and injury; 8, formed by thermal discoloration is obvious. Not only in order to ensure that the use of imported bearing performance, especially in machinery and equipment operation, better progress in peace. Bearing use have not obvious damage to the requirements in a timely manner in the process of change, or import bearings will incur machinery can't stop running, and form a don't want to hurt.
