drawn cup needle roller bearings HK5520 bearing 55*63*20mm
Needle roller bearing is a special type of roller bearing which uses long,thin cylindrical rollers resembing needles.Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. Like all bearings, they are used to reduce the friction of a rotating surface.
Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.
