Heavy Duty Needle Roller Bearings (Machined)

Needle Roller Bearings are bearings for rotary motion that use needle-shaped thin rollers as rolling elements. Compared to ball bearings, they have low sectional height and large load capacity. As a machine part, they help save space by making the whole machine compact. They play an important role in a wide range of products such as automobiles, motorcycles, printing machines, industrial robots and construction machinery.
