Needle roller bearing is roller bearing which has a cylindrical roller, relative to its diameter roller is thin and long called needle roller. Although the bearing has a small cross-section but it still has high load capacity, when its diameter size and load capacity are same with other types of bearing, it is outside diameter size is minimum, especially suitable for the limited size of the radial installation supporting. And according to the different occasions, can choose the bearing without inner ring or needle roller and cage assemblies. Needle roller bearing can be divided into the following categories according to its structure: (1) enclosed stamping outer ring needle roller bearing (2) inner ring needle roller bearing (3) without inner ring needle roller bearing/bracket will be without inner ring needle roller bearings (4) with cage needle bearing and without cage needle bearing (5) no guard needle roller bearing (6) the self-aligning roller bearings (7) composite needle/ball bearings (8) composite needle/thrust ball bearing (9) composite needle/cylindrical roller thrust bearing. The needle roller bearing which it is outer ring with a knurled is more conducive to be positioning, can be product when the inner diameter size above 3.
