What is Needle Roller Bearing?
A needle roller bearing is a specific variety of roller bearing which employs extended, slim cylindrical rollers loo ept like sewing needles. Rollers of ordinary roller bearings are only somewhat more time than their diameter, but needle rollers are at least four times lengthier than their diameter. Like all the other bearings, they are utilised to lessen the friction of rotating area.
Compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface location in speak to with the raceways, so they can assist a higher radial load but not axial load. They are also thinner, so they need considerably less clearance among the axle and the bordering construction.
Needle bearings are widely used in ept factors this sort of as rocker arm pivots, pumps, compressors, and transmissions. The push shaft of a rear-wheel generate vehicle usually has at the very least eight needle bearings (4 in every single U joint) and frequently a lot more if it is specifically lengthy, or operates on steep slopes.
Assorted sorts of needle bearings are available in a vast assortment of dimensions and tolerances, for a multitude of applications such as gearboxes, automotive electrical power transmission systems, two and 4 stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are offered in single or double row, reliable or split cage, metric and inch measurements. Solitary and double row bearings are accessible with or without ribs, and with or without having interior rings.
