China Custom Combined Needle Roller Bearings with Free Design Custom

Combined Needle Roller Bearings

Our combined needle roller bearings consist of a radial needle roller bearing and a thrust bearing. The combination can be Needle roller & angular contact ball bearings, Needle roller & thrust ball bearings, and Needle roller & cylindrical roller thrust bearings. They can accommodate both radial and axial loads. They are particularly suitable for applications where other types of locating bearing arrangements occupy too much space, the axial loads are too heavy, the speeds are too high, or the lubricant is inadequate for meetings with simple thrust washers.

  • NKXR series.

Features of combined needle roller bearings

  • Locating bearing arrangement
    Accommodate combined radial and axial loads in 1 or both directions.
  • Low cross-section
    In applications where less space is available, combined needle roller bearings offer a very compact solution.
  • High carrying capacity
    Owing to their large number of rolling elements, combined needle roller bearings have a high load-carrying capacity.

Applications of combined needle roller bearings

Our combined bearings can be used in different applications, for example:

  • machine tools;
  • wire-hooding machines;
  • capping machines;
  • etc.
