How to read SKF 31326 X
- 313Series
- Tapered roller bearings, 313 series. For the same bore, each series has a different outside diameter and width.
- 26Bore
- 130 mm bore: 26 × 5.
- XSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
31326 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF X series tapered roller bearings are components designed to withstand radial and axial loads in both directions. Their tapered geometry allows linear contact that distributes loads better, ideal for applications with moderate to high demands. MR Accesorios Industriales sells this line.
The designation of these bearings combines a basic number and the suffix X, which indicates dimensions according to international standards. For example, 31320 X and 32004 X share the suffix but differ in size and load capacity. The basic number defines the bore diameter and the dimension series; the higher the number, the larger the size. The suffix X indicates that the main dimensions comply with standardized specifications, which facilitates interchangeability.

These bearings are used in a wide variety of industrial applications in Argentina. They are found in gearboxes, transmission shafts, vehicle wheels, agricultural machinery, mining equipment and transport systems. Industries such as food, petrochemical and metallurgical rely on them to withstand combined loads and tilting moments. Their ability to work in severe conditions makes them suitable for environments with dust, vibration or moderate temperatures.
To correctly select a tapered roller bearing, take into account the radial and axial load, the rotational speed and the available space. It is essential to verify the mounting: tapered rollers require precise axial adjustment to achieve the correct internal clearance. Lubrication must be the one indicated according to the working regime, and sealing protects against contaminants. Alignment between shaft and housing is critical to avoid premature wear. Follow the manufacturer's recommendations for each application.
As for equivalents, SKF tapered roller bearings can be interchanged with those of other brands that follow the same dimensional standards, such as ISO or DIN. However, not all suffixes match between manufacturers; therefore, always verify the complete code and tolerances. The SKF X series usually has equivalents in other recognized brands, but it is essential to confirm dimensions and capacities before replacing. MR Accesorios Industriales can advise you on the selection.

Frequently Asked Questions
- What are the dimensions of the SKF 31326 X bearing?
- The SKF 31326 X bearing has a 130 mm bore, a 280 mm outside diameter and a 72 mm total width (130 x 280 x 72 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 31326.
- What does the X suffix mean on SKF bearings?
- The X suffix indicates that the main dimensions of the bearing comply with international standards, which facilitates interchangeability with other manufacturers that follow the same specifications. It does not change the load capacity or the internal design.
- How do I choose the right tapered roller bearing?
- You must consider the radial and axial load, speed, space and environmental conditions. Axial adjustment and lubrication are also key. Consult technical catalogs or get advice from us to select the correct code.
- Are SKF X series bearings interchangeable with other brands?
- Yes, as long as the dimensions and tolerances match according to standards. But suffixes can vary between manufacturers, so verify the complete code. We can help you find the right equivalent.
