Needle Roller Bearing

Needle roller bearing

Needle roller bearing is equipped with thin and long roller, so the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearing, the outer diameter is the smallest, especially suitable for the bearing result of radial installation size is limited.According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway.
