What loads can the SKF NKX 25 Z accommodate?

This combined bearing accommodates radial loads and single-direction axial loads simultaneously.

What are the dimensions of this bearing?

The bearing has an inside diameter of 25 mm, an outside diameter of 37 mm, and a width of 30 mm.

What is the purpose of the cover cap (Z suffix)?

The steel cover caps the thrust section to retain lubricating grease and prevent dirt ingress.

Can the SKF NKX 25 Z handle double-direction axial loads?

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

Does this bearing include an inner ring?

No, the needle roller section runs directly on a hardened and ground shaft or requires a separate inner ring.

Compact support with Skf NKX 25 Z

Practical benefits

Handles combined machine loads: You support both radial and single-direction axial forces simultaneously with a single, highly rigid bearing assembly.
Space saving low cross section: Its low cross-sectional height allows you to fit reliable bearing arrangements into extremely compact housings.
Effective grease retention cover: The integrated steel cover keeps lubricant inside the thrust section while protecting internal components from contamination.

In a nutshell

The right choise for

With the Skf nkx 25 z combined needle roller and thrust ball bearing, you handle radial loads and single-direction axial forces simultaneously within a single compact assembly. Thanks to its low cross-sectional height and 25X37X30 mm dimensions, you easily fit this bearing into tight housing spaces in gearboxes, machine tools, and drive systems. The integrated steel cover retains lubricating grease inside the thrust section and keeps dirt out during continuous operation. This allows you to optimize installation space on rotating shafts without compromising on load capacity.

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.
