 needle roller bearing

Needle Roller Bearings (Needle bearing) is a roller with a cylindrical roller bearings, relative to its diameter, both the thin and long rollers, this is called needle roller. Despite its smaller cross-section, still has a higher load bearing capacity, therefore, especially suitable for the radial space-constrained occasions

 

A 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 themselves, and an outer race(sometimes housing itself).
