Although needle bearing has a small section, the bearing still has a high load bearing capacity, needle bearing is equipped with a thin and long roller, so the radial structure is compact, the inside diameter size and load capacity of the same as other types of bearings, the outer diameter is small, especially suitable for radial installation size of the limited supporting structure. 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. This kind of bearing can bear only radial load.

This kind of bearing can bear only radial load. Needle roller bearing has a large bearing capacity and is suitable for mounting the supporting structure with limited size. The surface of the journal is hardened as the rolling surface, and the bearing is loaded into the seat hole with pressing fit, and there is no need to position it axially. Product parameters:
Application: Paper making machinery, reduction gear, railway vehicle axles, rolling mill gearbox bearing block, crusher, vibrating screen, printing machinery, etc
