The needle roller bearing is a bearing which uses small cylindrical rollers. They are used to reduce friction of a rotating surface. Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact.

The typical structure consists of a needle cage which orients and contains the needle rollers, the needle rollers thems.elves, and an outer race (sometimes the housing itself).

Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.

Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.

needle roller bearing classification :

1. Radial needle roller and cage assemblies

2. NA, NKI type needle roller bearings

3. RNA, NK model without inner ring needle roller bearings

4. Type HK stamping outer ring needle roller bearing

5. Type BK stamping outer ring needle roller bearing Mounted on the shaft end drawn cup needle roller bearing is open on both sides (1) and unilateral enclosed (2). Closed drawn cup base face can absorb small axial guiding force. Mounted on the shaft end drawn cup needle roller bearing is open on both sides (1) and unilateral enclosed (2). Closed drawn cup base face
