A needle bearing is a roller bearing with cylindrical rollers that are thin and long relative to their diameter. This is called needle rolling. Although it has a small cross-section, it has a high load-bearing capacity and is equipped with slender and long needle bearing rollers (roller diameter D<5mm, L/D>2.5, L is the length of the roller), so the diameter The radial structure is compact, and its outer diameter and load capacity are the smallest compared to other types of bearings. It is especially suitable for support structures with limited radial installation dimensions.

Depending on the occasion, a bearing without an inner ring or a needle roller and cage assembly can be used. When the journal surface of the bearing directly cooperates with the surface of the housing hole as the outer rolling surface of the bearing, to ensure that the load-bearing capacity and operation are consistent with the ferrule. For bearings with the same performance, the surface hardness, machining accuracy and surface quality of the shaft or housing hole raceway should be similar to those of roller bearing rings. Such bearings can only bear radial loads.

application:
Needle roller bearings are widely used in automobiles, compressors, construction, motors, food industry, household appliances and other fields. As a rolling body, it turns the world.
