When axial room is tight but the load is not, SKF AXK series needle thrust bearings are a practical choice. Each unit is a caged needle assembly that sits between two raceway surfaces and takes thrust in a single direction. MR Industrial Accessories supplies this SKF line and can help you match the right bearing and washers to your application.
Reading the AXK code is straightforward. AXK tells you it is a caged needle thrust bearing. The four digits that follow are metric dimensions: the first pair is the shaft diameter, the second pair is the outer diameter. So AXK 1024 fits a 10 mm shaft with a 24 mm outer diameter, and AXK 2035 a 20 mm shaft with a 35 mm outer diameter. This makes it easy to spot the size you need and to cross-reference between brands.
These bearings turn up in metallurgy, food processing, textiles and automotive work, wherever axial space is at a premium: gearboxes, pumps, compressors, machine tools and transmission equipment. Because they pack a high axial capacity into a very low section height, they are often chosen over thrust ball bearings when more rigidity is required.
Selection comes down to three things: the axial load, the running speed and the space available. The raceway surfaces matter just as much. Whether you use the faces of adjacent parts or dedicated washers, they need the right hardness and surface finish. Alignment must be precise and lubrication adequate, since needle thrust bearings do not tolerate angular misalignment. Check that the cage is centered and that contact surfaces are clean and free of damage.
Equivalents exist across brands that use the same dimensional designation, such as the AXK series from INA or NSK. Even so, tolerances and load ratings can differ from one maker to another. For a safe replacement, compare the critical dimensions and check with our team if anything is unclear.

Frequently asked questions
- What does the AXK code tell me?
- AXK means a needle thrust bearing with a cage. The following digits are metric: first two for shaft diameter, last two for outer diameter. AXK 1528, for instance, is a 15 mm bore and 28 mm outer diameter.
- Are raceway washers required?
- Yes. The AXK bearing is only the cage and needle set, so it needs suitable raceway surfaces. You can use hardened and ground faces of adjacent parts, or specific washers such as the AS or LS series, which we also supply.
- How can I tell if another brand's AXK bearing will fit?
- The dimensional designation usually matches across manufacturers, but tolerances and load capacity may differ. Compare bore, outer diameter and height. If you are unsure, send us the part number and measurements and we will help you find the right option.
