Description

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.
