Needle Roller / Thrust Ball Bearings



SKF supplies needle roller / thrust ball bearings in two series:

  • NX series with a full complement thrust ball bearing
  • NKX series with a thrust ball bearing with a cage

These combined bearings:

  • Consist of a radial needle roller bearing and a thrust ball bearing
  • Are supplied without an inner ring
  • Can be combined with an inner ring where the shaft cannot be hardened and ground
  • Can accommodate axial loads in one direction and, therefore, locate the shaft in one direction only
  • Can be mounted back-to-back, for short shafts and where changes in length due to thermal expansion are relatively minor.
