Decoding SKF 24180 ECAK30/W77
- 241Series
- Spherical roller bearings, 241 series. Series differ in outside diameter and width even when the bore is the same.
- 80Bore
- Bore 400 mm (80 × 5).
- ECAK30/W77Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24180 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 24180 ECAK30/W77 measures 400 mm across the bore and 650 mm across the outside diameter; its width is 250 mm (400 x 650 x 250 mm).

SKF spherical roller bearings are self-aligning, two-row components built to carry heavy radial loads together with axial loads in either direction, even when shaft flexing or misalignment is present. Because they tolerate a housing that is not perfectly concentric, they suit demanding industrial service. MR Industrial Accessories LLC supplies them as part of its SKF bearing range and helps customers match the right version to the equipment.
Reading the designation helps you understand what you are ordering. The numeric portion gives the dimension series. The letters EC point to an optimized design that uses a stamped steel cage with centered guidance. An A signals an internal variant, while K means the bore is tapered, with the taper depending on the code. The suffix /W identifies a special version, usually involving a coating or a particular treatment. Understanding these characters lets you assess the bearing's capabilities quickly.
Typical applications include conveyors, mills, crushers, vibrating screens, paper machines and mining equipment, wherever loads are heavy and misalignment can develop. They also appear in cement, steel, food processing and aggregate plants. Combined-load capacity and self-alignment make them a fit for long shafts, or for shafts mounted in structures that deform under temperature changes or mechanical stress.
Selection starts with the radial and axial loads, the rotational speed and the operating environment. A tapered bore is mounted on an adapter sleeve or directly on a tapered shaft, and internal clearance is set to suit the application. Lubrication should match temperature and speed; for hot or contaminated conditions, versions with special coatings are offered. Initial alignment is less critical than with other designs, but the permissible self-aligning angle should still be respected.
For equivalents, SKF spherical roller bearings can be interchanged with other brands that use the same ISO dimension series, such as FAG, NSK, NTN or Timken, as long as the version letters agree (cage, tapered bore, clearance). Load ratings and speed limits can differ from one maker to another, so it pays to check each alternative's data sheet. Suffixes are not always direct equivalents between brands, and a specialist can help sort that out.

Frequently asked questions
- SKF 24180 ECAK30/W77 bearing: what are its dimensions?
- SKF 24180 ECAK30/W77 measures 400 mm across the bore and 650 mm across the outside diameter; its width is 250 mm (400 x 650 x 250 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24180.
- What does the suffix K mean in the designation?
- The letter K indicates a tapered bore, generally with a 1:12 taper. This allows mounting on a tapered shaft or an adapter sleeve, which simplifies setting internal clearance and dismounting.
- When should a spherical roller bearing be used instead of a deep groove ball bearing?
- When loads are high or misalignment exists between shaft and housing. Spherical roller bearings carry higher radial and axial loads and tolerate angular misalignment, while deep groove ball bearings do not self-align.
- How do I know if an SKF bearing is interchangeable with another brand?
- Compare the ISO dimension series and the version suffixes (cage type, tapered bore, internal clearance). Even if main dimensions match, check load and speed ratings, which may differ between manufacturers.
