Which loads can this bearing accommodate?

It combines a needle roller bearing and a thrust ball bearing to support high radial loads and single-direction axial loads.

What are the exact dimensions of this NKX 70 Z bearing?

This bearing has an inside diameter of 70 mm, an outside diameter of 85 mm, and an overall width of 40 mm.

What is the purpose of the cover indicated by suffix Z?

The cover caps the thrust section and creates a gap-type seal to retain lubricating grease inside the bearing.

Is this combined bearing separable for mounting?

No, this is a non-separable bearing unit designed for compact installation where radial space is limited.

Does this bearing support axial forces in both directions?

No, the integrated thrust ball bearing is single-acting and accommodates axial loads in one direction only.

Robust performance by Skf

Practical benefits

Combined radial axial support: You accommodate both radial loads and single-direction axial thrust efficiently within a single compact bearing assembly.
Compact space saving profile: The low cross-sectional height allows you to fit reliable bearing arrangements into extremely restricted installation spaces.
Protected and greased design: The integrated steel cover retains lubricating grease and shields the thrust ball bearing section from external contamination.

In a nutshell

The right choise for

With the Skf nkx 70 z combined bearing, you support heavy radial forces and single-direction axial loads simultaneously within one compact unit. Measuring 70X85X40 mm, this non-separable bearing integrates a needle roller bearing and a thrust ball bearing, eliminating the need to install two separate bearings. Its low cross-sectional height saves valuable installation space in industrial gearboxes, drive systems, pumps, and machine tools. The integrated steel cover creates an effective seal that keeps lubricating grease inside while protecting the thrust section from external contamination.

Product description

These bearings consist of a radial needle roller bearing combined with a thrust ball bearing. Together they can accommodate both radial loads and axial loads in one direction. In addition, they can operate at relatively high speeds. Their low cross-sectional height makes the bearings particularly suitable for applications where other types of locating bearing arrangements occupy too much space. The thrust part is capped with a cover that forms a gap-type seal to retain the grease in the bearings.
