What is Needle Roller Bearing?
A needle roller bearing is a specific kind of roller bearing which makes use of lengthy, skinny cylindrical rollers loo ept like stitching needles. Rollers of common roller bearings are only slightly more time than their diameter, but needle rollers are at minimum 4 times more time than their diameter. Like all the other bearings, they are employed to minimize the friction of rotating area.
In comparison to ball bearings and other conventional roller bearings, needle bearings have a larger surface region in contact with the raceways, so they can assistance a higher radial load but not axial load. They are also thinner, so they call for considerably less clearance among the axle and the bordering structure.
Needle bearings are widely used in ept elements this sort of as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel generate vehicle normally has at the very least eight needle bearings (4 in every U joint) and typically a lot more if it is notably lengthy, or operates on steep slopes.
Various sorts of needle bearings are accessible in a extensive selection of dimensions and tolerances, for a multitude of applications such as gearboxes, automotive power transmission systems, two and four stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are provided in solitary or double row, strong or split cage, metric and inch sizes. Single and double row bearings are offered with or without having ribs, and with or without having internal rings.
