Machined Needle Roller Bearings with an inner ring are used if the shaft cannot be configured as a rolling bearing raceway. Owing to their large number of small-diameter rollers, needle roller bearings with machined rings have high stiffness.

Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes.
