How to read SKF 240/630 ECJ/W33
- 240Series
- Spherical roller bearings, 240 series. For the same bore, each series has a different outside diameter and width.
- /630Bore
- 630 mm bore.
- ECJ/W33Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
240/630 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF spherical roller bearings are self-aligning double-row components designed to withstand high radial loads and axial loads in both directions, even with misaligned shafts. They are used in heavy equipment where shaft deflection or mounting errors are common. At MR Accesorios Industriales we supply them and advise you so you choose the correct part number for your application.
The designation of this series combines letters and numbers that indicate design features. For example, in 240/630 ECJ/W33, the numeric prefix defines the dimension series; the letters ECJ indicate an optimized design with a sheet steel cage and special machining; and the suffix W33 indicates that the outer ring has a groove and three lubrication holes. Knowing these codes allows you to order the exact bearing your equipment needs.
These bearings are used in industries in Argentina such as cement, steel, mining, paper and material handling. They are present in crushers, mills, vibrating screens, heavy gearboxes, industrial fans and paper machines. Their ability to withstand misalignment makes them ideal for equipment where shafts deflect under load or where mounting is not perfectly rigid.
To select the correct bearing, take into account radial and axial load, rotation speed, type of lubrication and environmental conditions. Sealing is key: if there is dust or moisture, consider sealed variants. Internal clearance must be suitable for the operating temperature. During mounting, ensure careful initial alignment and correct lubrication; the bearing's self-aligning feature absorbs subsequent misalignment, but not serious installation errors.
Spherical roller bearings are interchangeable between manufacturers if the main dimensions and suffix design match. A code with W33 can be replaced by another brand that also has a lubrication groove and holes. However, always verify tolerances and clearance, as they can vary between brands. For accurate equivalents, consult us with the full part number and we will help you find the right option.

Frequently Asked Questions
- What are the dimensions of the SKF 240/630 ECJ/W33 bearing?
- The SKF 240/630 ECJ/W33 bearing has a 630 mm bore, a 920 mm outside diameter and a 290 mm width (630 x 920 x 290 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 240/630.
- What does the W33 suffix mean in a spherical roller bearing?
- The W33 suffix indicates that the outer ring has a circumferential groove and three distributed holes to facilitate lubrication. This allows the bearing to be relubricated more efficiently, especially in applications with high loads or moderate speeds.
- How do I know if I can replace a bearing from one brand with another brand?
- You must compare the main dimensions (bore, outer diameter and width), cage type, internal clearance and special suffixes. If they match, replacement is possible. Still, consult us with the full part number to verify compatibility and avoid problems.
- What care does the mounting of a spherical roller bearing require?
- It is important to align the housings well, lubricate correctly and apply the proper fit on the shaft and housing. The bearing's self-aligning capability compensates for small misalignments, but not large mounting errors. Follow the manufacturer's recommendations for each application.
