Do you know what is Needle Roller Bearings

Needle roller bearing

Needle roller bearing is a bearing which uses small cylindrical rollers. They are used to reduce friction of a rotating surface.

Needle roller bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings . 

And there is less added clearance (difference between the diameter of the bearingand the diameter of the shaft),

so the Needle roller bearings 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.

Thrust needle bearings are flat and use a radial pattern of needles,Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft.

Needle bearings are widely used in engine components like rocker arm pivots

Needle bearings are widely used in sewing machines, various gap-cars, fitness equipment, cars, motors, electric tools, entertainment tools, textile and printing machines, and also in engineering, hydraulic cylinders, forging machines, construction machinery.
