Product Details

Needle roller cage bearing NKS 65

Specification:

1.Needle roller bearing is a cylindrical roller of roller bearings, relative to its diameter, roller is thin and long.This is called needle roller.Although has a small cross-section, bearing still has high load capacity.

2.Needle bearing with fine and long roller, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting results.

3.In order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway.

Application:

Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes.
Additional clarification of needle roller: According to "Marks' Standard Handbook for Mechanical Engineers", a needle bearing is a roller bearing with rollers whose length are at least four times their diameter.
