Needle roller bearing is a roller bearing with cylindrical rollers. Compared with its diameter, the rollers are both thin and long. This kind of roller is called a needle roller. Although it has a small section, the bearing still has a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact. Its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest. It is especially suitable for supporting structures with limited radial installation size.

Scope of application

The cross-sectional height of needle roller bearings is small, but the bearing still has a high load bearing capacity, so it is especially suitable for occasions with limited radial space, including automobiles, motorcycles, motors, machine tools, aerospace equipment, office equipment and other industrial machinery.
