Needle bearing characteristics and uses:

Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3~10 times the diameter and the diameter is generally not more than 5mm), so the radial structure is compact, and the inner diameter and load capacity are the same as other types of bearings. The smallest diameter, especially suitable for radial mounting size limited support results. Depending on the application, the inner ringless bearing or needle roller and cage assembly can be used. The bearing surface and the housing hole surface are directly matched with the bearing. As the inner and outer rolling surfaces of the bearing, in order to ensure the same load capacity and running performance as the ferrule bearing, the hardness of the shaft or shell hole raceway surface, machining accuracy and surface quality should be similar to the raceway of the bearing ring. The bearing can only withstand radial loads. SHINE bearings

The free-standing bearing consists of a raceway ring and a needle roller and cage assembly. It can be combined with a thin rolled raceway (W) for stamping or a thick raceway (WS) for cutting. Precision-stamped raceway ring and integral bearing consisting of needle roller and cage assembly

Can withstand one-way axial load

This type of bearing occupies a small space, which is conducive to the mechanical compact design

Most use only the needle roller and cage assembly, and the mounting surface of the shaft and housing is used as the raceway surface.

Mainly applicable cage: steel stamping and holding, synthetic resin forming cage

Main uses: shifting devices for automobiles, cultivators, machine tools, etc.
