Combined Needle Roller Bearings

Combined needle roller bearings are used for two purposes; for applications requiring high accuracy and combined transmission of large radial and axial forces.

Combined type needle roller bearings are combinations of a radial bearing and a thrust bearing. Caged needle roller bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings.

They are compact, very economical, and can be subjected to radial and axial loads simultaneously.

They are widely used for machine tools, textile machinery and industrial machinery.

Bearing Series:

• NAX, NAXI, NKX – needle roller bearing combined with thrust ball bearing
• NBX, NBXI, NKXR – needle roller bearing combined with thrust cylindrical roller bearing

If a lighter and more precise machine design is required, needle roller bearings combined with angular contact ball bearings are used. These combined bearings can withstand heavy radial loads and unidirectional axial loads simultaneously.

Bearing series:NATA, NATB, NKIA59, NKIB59
