Needle Roller Bearings

A needle roller bearing is a bearing which uses small cylindrical rollers.The difference between a needle roller bearing and roller bearing is the ratio of diameter and length of their rollers.

Needle roller bearings are equipped with thin and long rollers (3 to 10 times the diameter of the roller and no more than 5 mm in diameter), so the radial structure is compact, and the inner diameter and load capacity are the same as other types of bearings.
