Needle Roller Bearings

These are roller bearings with cylindrical rollers. The rollers are thin and long compared with their diameters. This kind of roller is called as needle roller. Although they have smaller cross section, the bearings can still bear higher load bearing capacity, therefore, they are especially used for limited radial space.

Main Applications: Elevator accessories, plastic machinery, office equipment, medical equipment, stepper motor, graduating device and speed change gear, pressure rotor, fitness and sports apparatus.
