How to read SKF 24180 ECAK30/W77
- 241Series
- Spherical roller bearings, 241 series. For the same bore, each series has a different outside diameter and width.
- 80Bore
- 400 mm bore: 80 × 5.
- ECAK30/W77Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
24180 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF spherical roller bearings are two-row self-aligning components designed to withstand high radial loads and axial loads in both directions, even when the shaft is subject to flexing or misalignment. Their self-aligning design allows them to operate correctly even when the housing is not perfectly concentric, making them ideal for demanding industrial applications. At MR Accesorios Industriales we sell them as part of our SKF bearing line, with technical advice to select the right version for each piece of equipment.
The designation of these bearings combines letters and numbers that indicate design features. The number identifies the dimension series; the letters EC indicate an optimized design with a stamped steel cage and centered guidance; the A indicates an internal variant; the K means the bore is tapered (the taper may vary depending on the code); and the suffix /W corresponds to a special version, generally with a coating or particular treatment. Knowing these codes allows you to quickly interpret the bearing's capabilities.
These bearings are used in equipment where loads are high and misalignment may occur, such as conveyor belts, mills, crushers, vibrating screens, paper machines and mining equipment. In Argentina, they are common in the cement, steel and food industries and in aggregate processing plants. Their ability to withstand combined loads and their self-alignment make them suitable for long shafts or shafts mounted in structures that undergo deformation from temperature or mechanical stress.
To correctly select a spherical roller bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. If the bore is tapered, mounting is done on an adapter sleeve or directly on a tapered shaft, and the internal clearance is adjusted according to the application. Lubrication must be chosen according to temperature and speed; for high temperatures or contaminated environments, versions with special coatings are available. Initial alignment is less critical than in other types, but it is advisable to verify that the permissible self-aligning angle is not exceeded.
As for equivalents, SKF spherical roller bearings can be interchanged with those of other brands that follow the same ISO dimension series, such as FAG, NSK, NTN or Timken, provided the version letters match (cage, tapered bore, clearance). However, load ratings and speed limits may vary between manufacturers, so it is advisable to check the data sheet of each alternative. Each brand's own suffixes are not always direct equivalents; a specialist can guide you.

Frequently Asked Questions
- What are the dimensions of the SKF 24180 ECAK30/W77 bearing?
- The SKF 24180 ECAK30/W77 bearing has a 400 mm bore, a 650 mm outside diameter and a 250 mm width (400 x 650 x 250 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 24180.
- What does the suffix K mean in the designation?
- The letter K indicates that the bearing has a tapered bore, generally with a 1:12 taper. This allows it to be mounted on a tapered shaft or an adapter sleeve, which makes it easier to adjust the internal clearance and to dismount.
- When should a spherical roller bearing be used instead of a deep groove ball bearing?
- When loads are high or there is misalignment between shaft and housing. Spherical roller bearings withstand higher radial and axial loads and tolerate angular misalignment, whereas deep groove ball bearings do not self-align.
- How do I know if an SKF bearing is interchangeable with another brand?
- You must compare the ISO dimension series and the version suffixes (cage type, tapered bore, internal clearance). Even if the main dimensions match, check the load and speed ratings, which may differ between manufacturers.
