Description	Needle roller bearings rolling is an independent component of its cage and guide the two wide spacing, can accurately guide the needle, the needle can maintain the correct position, A needle roller bearing is a bearing which uses small cylindrical rollers. They are used to reduce friction of a rotating surfa.
Use	Radial needle roller bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of The products are applied to areas such as textile machinery, printing machinery, tobacco machinery, engineering machinery, sewing machinery, food-needles. packing machinery, motorcycles, mopeds, power tools, automobiles, office equipment, auto-laundry machines and mining machinery.
Materials	Needle roller bearing: Chrome steel, Carbon steel, Stai GCr15, High Carbon steel GCr-11, and so on
Feature	Needle roller 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 a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race(sometimes housing itself).
