SKF spherical roller bearings are self-aligning bearings with two rows of rollers, designed for shafts where high radial loads coexist with axial loads and some misalignment between housing and shaft. They are used in continuous process equipment, where the mounting is not always perfectly aligned and the load is not even. MR Accesorios Industriales quotes them by part number, with more than 80 years of experience in industrial distribution in Buenos Aires, Argentina.
The designation is read in parts. In the example part number 248/530 CAK30MA/W20, the numeric prefix 248 identifies the dimension series and the number after the slash indicates the bore diameter: 530. Then come the execution letters, in this case CAK30MA and W20, which are part of the part number and distinguish variants within the same series. To request the bearing, it is enough to send the complete part number as it appears on the drawing or on the equipment plate.
They are common bearings in steel, cement, mining, paper, aggregate processing and heavy power transmission. They appear in gearboxes, conveyor belts, mills, screens, industrial fans and continuous process machines, where the shaft works with deflection and the housing does not guarantee perfect alignment. In Argentine plants they are found both in new equipment and in scheduled maintenance replacements.
To select correctly, look at the radial and axial load the shaft will bear, the rotation speed and the admissible degree of misalignment of the mounting. During mounting, take care of the cleanliness of the seat, the correct support on the ring and the initial alignment of the assembly; a poor initial alignment punishes the rollers. Lubrication and relubrication must follow the equipment manufacturer's recommendation, and the shaft and housing fit must respect the tolerances indicated for this type of bearing.
When the customer brings a part number from another brand, the equivalent can be found by series and by bore, outer diameter and width dimensions. Interchangeability between manufacturers is resolved by comparing those three data points and the type of execution, not just the series number. If the part comes without identification, it is advisable to measure the bore, outer diameter and width, and send those values along with a photo of the bearing and the seat.
If you have the part number of the SKF spherical roller bearing you need, send it via WhatsApp to MR Accesorios Industriales and we will quote it. You can also write to us with the equipment model or the shaft and housing dimensions, and we will indicate the compatible alternative. We sell and distribute SKF bearings in Buenos Aires, Argentina, along with the power transmission and mounting line.

Frequently Asked Questions
- What are the dimensions of the SKF 248/530 CAK30MA/W20 bearing?
- The SKF 248/530 CAK30MA/W20 bearing has a 530 mm bore, a 650 mm outside diameter and a 118 mm width (530 x 650 x 118 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 248/530.
- How do I request a quote for an SKF spherical roller bearing?
- Send via WhatsApp the complete part number that appears on the drawing or on the equipment plate, for example 248/530 CAK30MA/W20. With that data we will quote the bearing. If you do not have the part number, send the bore, outer diameter and width dimensions, and a photo of the part.
- What data do I need to choose the correct bearing?
- Radial and axial load of the shaft, rotation speed, bore diameter and type of mounting. It also helps to know whether the equipment works with misalignment between housing and shaft. With that data we will guide you on the series and execution that corresponds to your application.
- Can you get the equivalent of a bearing from another brand?
- Yes. If you bring the part number from another manufacturer, we compare it by series and by bore, outer diameter and width dimensions, and quote you the SKF equivalent. We also resolve cases when the part comes without identification, based on the measurements taken in the workshop.
