What is Needle Roller Bearing?
A needle roller bearing is a specific type of roller bearing which uses extended, thin cylindrical rollers loo ept like stitching needles. Rollers of ordinary roller bearings are only a bit more time than their diameter, but needle rollers are at minimum four times more time than their diameter. Like all the other bearings, they are utilised to reduce the friction of rotating surface area.
In contrast to ball bearings and other conventional roller bearings, needle bearings have a larger surface spot 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 demand considerably less clearance between the axle and the surrounding construction.
Needle bearings are widely used in ept factors these kinds of as rocker arm pivots, pumps, compressors, and transmissions. The push shaft of a rear-wheel push automobile generally has at minimum eight needle bearings (4 in every U joint) and frequently more if it is especially long, or operates on steep slopes.
Assorted kinds of needle bearings are obtainable in a extensive selection of sizes and tolerances, for a multitude of applications such as gearboxes, automotive energy transmission programs, two and 4 stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are offered in single or double row, sound or split cage, metric and inch sizes. Solitary and double row bearings are available with or with no ribs, and with or with out inner rings.
