Decoding SKF 248/530 CAK30MA/W20
- 248Series
- Spherical roller bearings, 248 series. Series differ in outside diameter and width even when the bore is the same.
- /530Bore
- Bore: 530 mm.
- CAK30MA/W20Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
248/530 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 248/530 CAK30MA/W20 measures 530 mm across the bore and 650 mm across the outside diameter; its width is 118 mm (530 x 650 x 118 mm).

SKF spherical roller bearings are self-aligning, with two rows of rollers. They suit shafts where high radial loads occur together with axial loads and some misalignment between housing and shaft. Continuous process equipment often runs with imperfect mounting alignment and uneven load, which is where these bearings fit. MR Industrial Accessories LLC supplies them to customers across the United States, Canada, Mexico and South America, quoting by part number through WhatsApp or email.
Reading the designation helps when you order. Take 248/530 CAK30MA/W20: the prefix 248 is the dimension series, and the digits after the slash give the bore diameter, 530. The letters that follow, CAK30MA and W20, are execution codes and belong to the part number, separating variants inside one series. Send the full part number exactly as it appears on the drawing or equipment plate.
You will find these bearings in steel, cement, mining, paper, aggregate processing and heavy power transmission. They run in gearboxes, conveyor belts, mills, screens, industrial fans and continuous process machines, where the shaft deflects and the housing does not sit perfectly aligned. Replacements come up both on new equipment and during scheduled maintenance.
Selection comes down to the radial and axial load on the shaft, the rotation speed and how much misalignment the mounting can accept. At mounting, keep the seat clean, support the ring correctly and align the assembly from the start; poor initial alignment punishes the rollers. Follow the equipment manufacturer's recommendation for lubrication and relubrication, and respect the specified tolerances for shaft and housing fits.
When a part number comes from another brand, the equivalent is found by series and by bore, outer diameter and width. Interchangeability between manufacturers is settled by those three dimensions plus the execution type, not by the series number alone. If a part arrives without identification, measure bore, outer diameter and width, and send the values with a photo of the bearing and the seat.
Send the part number of the SKF spherical roller bearing you need by WhatsApp or email, and the team replies promptly with a quote. You can also write with the equipment model or the shaft and housing dimensions, and they will suggest the compatible alternative. MR Industrial Accessories LLC also covers the power transmission and mounting line.

Frequently asked questions
- SKF 248/530 CAK30MA/W20 bearing: what are its dimensions?
- SKF 248/530 CAK30MA/W20 measures 530 mm across the bore and 650 mm across the outside diameter; its width is 118 mm (530 x 650 x 118 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 248/530.
- How do I request a quote for an SKF spherical roller bearing?
- Send the complete part number from the drawing or equipment plate by WhatsApp or email, for example 248/530 CAK30MA/W20. Without the part number, send the bore, outer diameter and width dimensions plus a photo of the part.
- What data do I need to choose the correct bearing?
- Radial and axial load on the shaft, rotation speed, bore diameter and mounting type. It also helps to know whether the equipment runs with misalignment between housing and shaft.
- Can you get the equivalent of a bearing from another brand?
- Yes. Bring the part number from the other manufacturer and it is compared by series and by bore, outer diameter and width, then the SKF equivalent is quoted. Parts without identification can be resolved from workshop measurements.
