What is Needle Bearing?
A needle bearing is a specific sort of roller bearing which makes use of long, skinny cylindrical rollers bathroom ept like sewing needles. Rollers of common roller bearings are only marginally more time than their diameter, but needle rollers are at the very least four instances longer than their diameter. Like all the other bearings, they are employed to reduce the friction of rotating surface area.
Compared to ball bearings and other standard roller bearings, needle bearings have a bigger surface area spot in speak to with the raceways, so they can assist a higher radial load but not axial load. They are also thinner, so they call for much less clearance between the axle and the bordering structure.
Needle bearings are widely used in ept factors such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel push automobile generally has at the very least 8 needle bearings (four in each U joint) and often far more if it is specifically lengthy, or operates on steep slopes.
Diverse varieties of needle bearings are accessible in a extensive variety of dimensions and tolerances, for a multitude of apps this sort of as gearboxes, automotive energy transmission systems, two and 4 stroke engines, planetary gear sets and air compressors.
Needle roller and cage assemblies are provided in single or double row, sound or split cage, metric and inch measurements. Solitary and double row bearings are obtainable with or without ribs, and with or without interior rings.
