needle bearing
NACHI needle bearing
With thin and long needle bearing roller (roller length diameter of 3 to 10 times the diameter of generally not more than 5mm), so the radial structure is compact, its internal diameter and load capacity of the same with other types of bearings, minimum diameter, especially for radial bearing mounting dimensions restricted results. According to use different, and can be used without inner ring of the bearing or needle roller and cage assemblies, this time with the journal bearing surface and the shell to match the surface directly as a bearing hole, the outer rolling surface, in order to ensure the load capacity and operational performance and have the same ring bearings, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing ring. Such bearings can only bear radial load.
Needle bearings are divided into:
1. Radial needle roller and cage assemblies
2.NA, NKI-type needle roller bearings
3.RNA, NK-type needle roller bearings without inner ring
4.Needle roller bearings, HK-type
5.Needle roller bearings, BK-type
