Needle roller bearing is a bearing with cylindrical rollers with diameter less than length. The roller end shrinks slightly to improve the line contact between the roller and the raceway. This prevents peak stress at both ends of the needle roller, thereby extending the service life of the bearing. Although the cross-section of needle roller bearings is small, they have high bearing capacity. Therefore, they are very suitable for bearing configurations with limited radial space.

Needle roller bearing can be divided into radial bearing and thrust bearing according to the direction of bearing load. Among them, radial bearings include: various series of stamping outer ring type, solid type, and special-purpose bolt type and retaining ring type roller needle bearings.
