What are the characteristics of needle roller bearings


Needle roller bearing is a roller bearing with cylindrical rollers. The rollers are thin and long relative to their diameters. This kind of roller is called needle roller. Although it has a small section, the bearing still has a high load bearing capacity.

Needle roller bearing is equipped with thin and long rollers, so its radial structure is compact. Its inner diameter and load capacity are the same as those of other types of bearings, and its outer diameter is very small. It is especially suitable for supporting structures with limited radial installation size.

Needle roller bearing

Bearing without inner ring or needle roller and cage assembly can be selected according to different applications. At this time, the journal surface and housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. To ensure the same load capacity and operating performance as the bearing with ring, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial load.
