Needle roller bearings use cylindrical rollers rather than spherical rollers. The length of the cylinder should be at least four times its diameter. Compared to ball bearings, a large amount of the surface area of a needle bearing is in contact with the bearing outer surface. Needle bearings are also more compact than ball bearings because there is less added clearance. Typically, a needle bearing consists of a needle cage to contain and orient the cylinders, the rollers and an outer race.
There are two kinds of needle bearings: radial needle bearings, which are cylindrical, and thrust roller bearings, which are flat and use a radial pattern of bearings. Full-complement bearings have rib-guided cylindrical rollers and inner rings and outer rings. They can bear a high radial load and are suited to the most compact designs. This type of bearing is frequently used in vehicle components such as drive shafts, transmissions, compressors, pumps or rocker arm pivots.
