What is Needle Roller Bearing?
A needle roller bearing is a unique sort of roller bearing which uses extended, slender cylindrical rollers loo ept like stitching needles. Rollers of normal roller bearings are only slightly for a longer time than their diameter, but needle rollers are at least four instances for a longer time than their diameter. Like all the other bearings, they are utilized to lessen the friction of rotating floor.

In contrast to ball bearings and other conventional roller bearings, needle bearings have a larger surface area in get in touch with with the raceways, so they can help a better radial load but not axial load. They are also thinner, so they require significantly less clearance amongst the axle and the surrounding structure.

Needle bearings are widely used in ept parts these kinds of as rocker arm pivots, pumps, compressors, and transmissions. The push shaft of a rear-wheel drive vehicle generally has at minimum 8 needle bearings (4 in every U joint) and usually far more if it is specifically extended, or operates on steep slopes.

Diverse kinds of needle bearings are offered in a wide variety of sizes and tolerances, for a multitude of applications such as gearboxes, automotive energy transmission systems, two and 4 stroke engines, planetary equipment sets and air compressors.

Needle roller and cage assemblies are provided in one or double row, sound or break up cage, metric and inch dimensions. Solitary and double row bearings are accessible with or with out ribs, and with or without having inner rings.
