Needle bearings are important components in mechanical equipment.
Its main function is to support the mechanical torsion body to reduce the mechanical load friction coefficient of the equipment in the transmission
process. According to different load deflection or nominal contact angle, needle roller bearings are divided into radial needle roller bearings and
thrust bearings. According to the variety of rotating elements, they are: ball bearings and rolling bearings. According to whether the needle roller
bearings can be aligned, they can be self-aligning bearings and non-aligning bearings (rigid needle roller bearings). 
According to the number of rows of the rotating body, it is respectively: single-row needle roller bearings, double-row needle roller bearings
and multi-row needle roller bearings. According to whether the parts can be peeled off, they can be divided into: clutchable pressure plate
and non-clutchable bearing. In addition, it is classified and managed according to the layout characteristics, styles and dimensions.
What are the classifications of needle roller bearings?
1) Centripetal needle roller and cage assembly
2) RNA, NKI type needle roller bearings
3) RNA and NK needle roller bearings without inner ring
4) HK type drawn outer ring needle roller bearing
5) BK type drawn outer ring needle roller bearing
The drawn cup needle roller bearings installed on the shaft end have double-sided open type (1) and single-sided closed type (2). The base end face of the closed drawn outer ring can withstand low axial guiding forces.
