Decoding SKF 24080 ECCJ/W33
- 240Series
- Spherical roller bearings, 240 series. Series differ in outside diameter and width even when the bore is the same.
- 80Bore
- Bore 400 mm (80 × 5).
- ECCJ/W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24080 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 24080 ECCJ/W33 measures 400 mm across the bore and 600 mm across the outside diameter; its width is 200 mm (400 x 600 x 200 mm).

Spherical roller bearings in the SKF ECCJ/W series are self-aligning units with two rows of rollers. They carry high radial loads together with axial loads in both directions, and they keep working when the shaft flexes or the mounting is not perfectly aligned. You will find them in heavy transmissions, mills, conveyors and mining equipment, where misalignment is a normal condition rather than an exception.
Reading the ECCJ/W code helps you confirm what you are ordering. The numeric prefix gives the size and dimension series. EC marks an optimized design with symmetrical rollers and a stamped steel cage. CJ identifies the steel cage with surface treatment. The final W means the outer ring has a lubrication hole and groove. Series examples include 24080 ECCJ/W33, 24168 ECCJ/W33 and 24172 ECCJ/W33. The W33 suffix adds the groove and three lubrication holes in the outer ring.
These bearings show up in cement, mining, steel, paper, wind power and material handling. Typical positions are ball mills, crushers, vibrating screens, large gearboxes, rotary kiln rollers and oilseed processing machinery. Combined loads and misalignment are the reasons they are specified there: equipment subject to vibration or shaft flexing tends to fatigue other bearing types early.
Selection comes down to radial and axial load, rotation speed and permissible misalignment. Mounting still calls for careful initial alignment, even though the bearing absorbs later deviations. Lubrication matters just as much, and the W33 groove and holes let you regrease from the outer ring. Check internal clearance and sealing against the environment; dusty or wet conditions may call for extra protection. The EC cage improves roller guidance and cuts friction.
Spherical roller bearings follow international dimension standards, so brands can be interchanged while keeping the same basic number and suffixes. When you look for a replacement, compare more than the numeric code: design, cage and lubrication suffixes can differ from one manufacturer to another. Not every suffix is equivalent across brands, so check the technical specifications for load and speed compatibility.

Frequently asked questions
- SKF 24080 ECCJ/W33 bearing: what are its dimensions?
- SKF 24080 ECCJ/W33 measures 400 mm across the bore and 600 mm across the outside diameter; its width is 200 mm (400 x 600 x 200 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24080.
- What does the W33 suffix mean on an SKF bearing?
- W33 indicates a groove and three lubrication holes in the outer ring. That lets you regrease the bearing from the outside without disassembling it, which simplifies maintenance in industrial applications.
- When should I use a spherical roller bearing?
- Use one when radial loads are high and misalignment between shaft and housing is possible, or when the shaft flexes under load. It also suits moderate axial loads in both directions at moderate speeds.
- Are SKF ECCJ/W bearings interchangeable with other brands?
- They share standardized dimensions, but suffixes can vary. For a safe replacement, verify that cage design, lubrication and internal clearance are equivalent. Send the complete part number and we will help you find the equivalent.
