How to read NSK 53336 XU
- 533Series
- Thrust ball bearings, 533 series. For the same bore, each series has a different outside diameter and width.
- 36Bore
- 180 mm bore: 36 × 5.
- XUSuffix
- NSK suffix: it defines the variant (sealing, cage, internal clearance or other features).
53336 is the standard (ISO) basic designation: it defines the type, the series and the bore.

The NSK XU series thrust ball bearing is a component designed to carry predominantly axial loads in one direction. Its construction with balls and flat rings suits applications requiring high thrust capacity and axial rigidity, such as gearboxes, pumps and lifting equipment.
The XU series designation is read from the number preceding it: examples 53226 XU, 53228 XU and 53230 XU correspond to single-direction thrust ball bearings with bore diameter according to the code. The XU suffix indicates a specific execution of the series, generally associated with a steel sheet cage and standard tolerances. To identify the exact size, the numeric code is the key reference: the higher the number, the larger the bore diameter.
These bearings are used in applications where the main load is axial and must be transmitted in a single direction. In Argentine industry, they are common in speed reducers, centrifugal pumps, industrial fans, rotary tables and lifting equipment. They also appear in machine tool spindles and clutch mechanisms. Their ability to withstand considerable thrust makes them suitable for environments with moderate vibration and medium speeds.
To select the correct thrust bearing, take into account the axial load it must carry, the rotation speed and the available space. It is essential to verify that the housing and shaft support surfaces are parallel and ground, since poor alignment generates additional loads and reduces service life. Lubrication can be with grease or oil; in high-speed applications, circulating oil is recommended. Sealing will depend on the environment: in the presence of dust or moisture, choose variants with shields.
As for equivalents, XU series thrust ball bearings can be interchanged with products from other brands that follow the same numeric designation and ISO dimensions. Always verify the bore, outer diameter and overall height before replacing. If you have another brand's code, at MR Accesorios Industriales we can tell you the equivalent NSK reference and quote the exact size you need.

Frequently Asked Questions
- What does the XU suffix mean on an NSK thrust bearing?
- The XU suffix identifies a specific execution within the NSK thrust ball bearing series. It is generally associated with a steel sheet cage and standard tolerances. To confirm the exact characteristics of your reference, contact us on WhatsApp with the complete code.
- How do I choose between a single-direction and a double-direction thrust bearing?
- The choice depends on whether the axial load acts in one direction or both. The single-direction type carries thrust in one direction; the double-direction type, in both. If your application has alternating loads, you need double-direction. Send us 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 the duty cycle. Contact us and we will tell you the best option for your case.
