For applications where the main load runs along the shaft, the NSK XU series thrust ball bearing is built to take axial force in a single direction. Its ball-and-flat-ring design is common in gearboxes, pumps and lifting equipment, where thrust capacity and axial rigidity matter.
The XU suffix marks a particular execution of the series, typically with a steel sheet cage and standard tolerances. The number in front of it sets the bore size: 53226 XU, 53228 XU and 53230 XU are single-direction thrust ball bearings, and the bore grows as that number rises. When you only have the numeric code, that is the reference to read first.
In service, these bearings handle axial load in one direction. They show up in speed reducers, centrifugal pumps, industrial fans, rotary tables and lifting equipment, as well as machine tool spindles and clutch mechanisms. Moderate vibration and medium speeds are within their range.
Selection comes down to three inputs: the axial load to be carried, the rotation speed and the space available. The shaft and housing support surfaces must be parallel and ground; misalignment adds load and shortens service life. Grease or oil both work for lubrication, with circulating oil preferred at higher speeds. In dusty or damp areas, consider shielded variants.
Interchange is possible with other brands that use the same numeric designation and ISO dimensions, but check bore, outer diameter and overall height before fitting. If you send us another manufacturer's code, we can point you to the equivalent NSK reference and quote the size you need.

Frequently asked questions
- What does the XU suffix mean on an NSK thrust bearing?
- It identifies a specific execution within the NSK thrust ball bearing series, generally with a steel sheet cage and standard tolerances. Send us the complete code on WhatsApp to confirm the exact characteristics of your reference.
- How do I choose between a single-direction and a double-direction thrust bearing?
- It depends on whether the axial load acts in one direction or both. A single-direction bearing carries thrust one way; a double-direction bearing carries it both ways. For alternating loads, you need the double-direction type. Share your equipment conditions and we will advise you.
- What lubrication do you recommend for a thrust ball bearing?
- For moderate speeds, lithium grease or similar is suitable. At high speeds or elevated temperatures, circulating oil is recommended. The final choice depends on the environment and duty cycle. Contact us and we will tell you the best option for your case.
