Needle Roller bearings NA2210 2RSR use a roller style rolling element to reduce friction of a rotating surface. Needle Bearings have a high load carrying capacity with a very small cross section height. They are available with or without an inner ring. The needle rollers are guided parallel to the axis using a cage retainer, thrust bearings can also be supplied with no retainer, which is referred to as a full complement of rollers.
Needle Roller bearing NA2210 2RSR have a larger surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less clearance, or the 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 heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions.
Needle Roller Bearing NA2210 2RSR is a bearing which uses small cylindrical rollers.The difference between a needle roller bearing and roller bearing is the ratio of diameter and length of their rollers, when the ratio of the diameter and the length of roller of a roller bearing is between the interval of 0.1 to 0.4, that roller bearing is called a needle roller bearing. They are used to reduce the friction of a rotating surface.
Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.
Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.
