Bearing Description

What is Needle Roller CZPT ?

A needle roller bearing is a particular type of roller bearing which uses CZPT , skinny cylindrical rollers looking like stitching needles. Rollers of regular roller bearings are only a bit CZPT er than their diameter, but needle rollers are at minimum 4 instances CZPT er than their diameter. Like all the other bearings, they are utilized to lessen the friction of rotating floor.

In comparison 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 assistance a greater radial load but not axial load. They are also thinner, so they require much less clearance between the axle and the surrounding structure.

Needle bearings are widely used in car components such as rocker arm pivots, pumps, compressors, and transmissions. The push shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (four in every single U joint) and frequently a lot more if it is specifically CZPT , or operates on steep slopes.

Various sorts of needle bearings are CZPT in a extensive selection of sizes and tolerances, for a multitude of applications such as gearboxes, automotive CZPT transmission systems, two and four stroke engines, planetary equipment sets and CZPT s.

Needle roller and cage assemblies are supplied in single or double row, reliable or split cage, metric and inch dimensions. Solitary and double row bearings are CZPT with or with out ribs, and with or without having inner rings.
