What is Needle Roller Bearing?
A needle roller bearing is a special variety of roller bearing which utilizes long, slim cylindrical rollers loo ept like stitching needles. Rollers of regular roller bearings are only a bit for a longer time than their diameter, but needle rollers are at least 4 occasions longer than their diameter. Like all the other bearings, they are utilised to minimize the friction of rotating floor.
When compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface location in make contact with with the raceways, so they can help a greater radial load but not axial load. They are also thinner, so they demand much less clearance in between 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 travel shaft of a rear-wheel travel car usually has at minimum eight needle bearings (four in every U joint) and typically much more if it is especially long, or operates on steep slopes.
Varied varieties of needle bearings are available in a extensive assortment of sizes and tolerances, for a multitude of applications such as gearboxes, automotive energy transmission systems, two and four stroke engines, planetary gear sets and air compressors.
Needle roller and cage assemblies are provided in single or double row, solid or split cage, metric and inch dimensions. Single and double row bearings are available with or without having ribs, and with or with out internal rings.
