NA 3080 Needle roller bearing

Type: NA K HK NK NKI CK NX RSTO STO AXK HF LR

Advantages:

Compact & High Capacity: Provide very high radial load capacity where radial space is extremely limited.

Economical: Some types (e.g., needle roller and cage assemblies) can run directly on hardened shafts and in housings, saving space and cost.

Applications: Widely used in transmissions, motorcycle connecting rods, automotive steering systems, and other compact spaces.

Needle roller bearings are equipped with thin, long rollers (the roller length is 3 to 10 times the diameter, and the diameter is generally no more than 5 mm), resulting in a compact radial structure. With the same inner diameter and load capacity as other types of bearings, they have the smallest outer diameter, making them particularly suitable for support structures where radial installation dimensions are limited. Depending on the application, the machining accuracy and surface quality of needle roller bearings should be combined with the bearing rings and the intended use. Needle roller bearings are bearing units composed of radial needle roller bearings and thrust bearing components.
