What is Needle Roller Bearing?
A needle roller bearing is a special variety of roller bearing which employs lengthy, skinny cylindrical rollers loo ept like sewing needles. Rollers of normal roller bearings are only slightly more time than their diameter, but needle rollers are at least 4 times for a longer time than their diameter. Like all the other bearings, they are utilized to minimize the friction of rotating surface.
Compared to ball bearings and other conventional roller bearings, needle bearings have a larger surface region in make contact with with the raceways, so they can assist a increased radial load but not axial load. They are also thinner, so they require considerably less clearance among the axle and the surrounding composition.
Needle bearings are widely used in ept elements this kind of as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel push motor vehicle usually has at least 8 needle bearings (4 in each and every U joint) and typically much more if it is especially lengthy, or operates on steep slopes.
Assorted kinds of needle bearings are obtainable in a wide selection of dimensions and tolerances, for a multitude of applications such as gearboxes, automotive power transmission systems, two and four stroke engines, planetary gear sets and air compressors.
Needle roller and cage assemblies are offered in solitary or double row, sound or break up cage, metric and inch dimensions. One and double row bearings are available with or with no ribs, and with or with out inner rings.
