Feature: 1. 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 an inner race (or sometimes merely a shaft), a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race.

Needle bearings are suitable when the rotational speed is relatively low.2. The grinding operation shaft's hardness 58-64hrc, surface rouyhness less than Ra0.2. 3. We can accept nonstandard item as custome's sample or drawings
