• Models like NK and NKS have flanges on the outer ring, which can limit the axial displacement of the rollers and withstand a certain axial force, ensuring the stable operation of the bearings under axial loads. They are commonly used in transmission systems with axial loads.

• A large number of models like RNA49 are suitable for different installation dimensions and load requirements, and are widely used in various industrial equipment, such as motors and transmissions.

• Types such as RNAO, NAO, RPNA, and PNA are fully separable. The outer ring, needle roller and cage assembly, and inner ring can be installed separately, facilitating installation and maintenance. In many applications, the needle roller and cage assembly can be installed with the outer ring or the shaft/inner ring according to the design, or inserted between the outer ring and the shaft/inner ring at the end.
