What are the applications of Needle Roller Bearings?
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.
Additional clarification of needle roller bearing: According to "Marks' Standard Handbook for
Mechanical Engineers", a needle bearing is a roller bearing with rollers whose length are at least
four times their diameter.
