Needle roller bearings have relatively small diameter cylindrical rolling elements whose length is much larger than their diameter. Compared with other types of rolling bearings, needle roller bearings have a small cross-sectional height and significant load-bearing capacity and rigidity relative to their volume. Also, because the inertial force acting on them is limited, they are an ideal choice for applications with an oscillating motion.
Needle roller 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.
Needle roller 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.
Needle roller bearings also work well in compact and lightweight machine designs and they serve as a ready replacement for sliding bearings.
If you are looking for needle roller bearing in India – NRB bearing is the one-stop solution for you. Founded in 1965, NRB was the first company to manufacture needle roller bearings in India. For over 40 years NRB has pioneered the leading edge of bearing technology, and today over 90% of vehicles on Indian roads run on NRB parts. Since its inception, NRB has grown beyond its signature product to offer a wide range of high-precision friction solutions not only in the automotive sector but across all mobility applications.
