What is Needle Roller Bearing?
A needle roller bearing is a special variety of roller bearing which uses long, thin cylindrical rollers loo ept like stitching needles. Rollers of common roller bearings are only a bit lengthier than their diameter, but needle rollers are at the very least 4 occasions lengthier than their diameter. Like all the other bearings, they are utilised to reduce the friction of rotating floor.
In comparison to ball bearings and other conventional roller bearings, needle bearings have a larger surface location in get in touch with with the raceways, so they can support a higher radial load but not axial load. They are also thinner, so they need considerably less clearance among the axle and the encompassing structure.
Needle bearings are widely used in ept components this sort of as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel travel motor vehicle normally has at minimum 8 needle bearings (four in every U joint) and often far more if it is specifically long, or operates on steep slopes.
Diverse kinds of needle bearings are accessible in a vast variety of dimensions and tolerances, for a multitude of applications such as gearboxes, automotive electricity transmission programs, two and four stroke engines, planetary equipment sets and air compressors.
Needle roller and cage assemblies are supplied in single or double row, strong or split cage, metric and inch sizes. One and double row bearings are available with or without ribs, and with or without having internal rings.
