Decoding SKF 24168 ECACK30/C3W33
- 241Series
- Spherical roller bearings, 241 series. Series differ in outside diameter and width even when the bore is the same.
- 68Bore
- Bore 340 mm (68 × 5).
- ECACK30/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24168 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 24168 ECACK30/C3W33 measures 340 mm across the bore and 580 mm across the outside diameter; its width is 243 mm (340 x 580 x 243 mm).

Spherical roller bearings from SKF are double-row, self-aligning parts built to carry heavy radial loads together with axial loads in either direction. Because the outer ring raceway is spherical, the bearing tolerates angular misalignment and shaft deflection, which suits equipment where alignment is hard to hold during mounting or operation. MR supplies this SKF line and assists with reading the designation so the replacement matches the application.
Each designation tells you how the bearing is built. Take 24168 ECACK30/C3W33: the numbers at the front set the dimension series, ECAC points to an optimized internal design with a stamped steel cage and specific machining, K30 means a tapered bore at 1:30, C3 means radial internal clearance above normal, and W33 means a lubrication groove with holes in the outer ring. Reading these suffixes correctly is what keeps a replacement order accurate.
Typical duty is found in cement, mining, steel, paper and aggregate processing. Crushers, vibrating screens, mills, gearboxes, industrial fans and paper machines rely on these bearings where loads run high and alignment is not ideal. Self-alignment limits the chance of early failure caused by shaft deflection or movement in the foundation.
Selection starts with radial and axial load, speed and the surrounding environment. A K30 bore calls for a tapered shaft seat or an adapter sleeve, so check the taper and set clearance with the radial measurement method. Grease or oil choice follows temperature and contamination level, and the W33 groove and holes make relubrication easier. Careful initial alignment and adequate sealing also support service life.
Interchange is possible with bearings from other makers that use the same dimensions and suffix system, such as FAG, NSK, NTN or Timken. Tolerances and radial clearance can still differ, so compare principal dimensions and load ratings before substituting. Send the original part number and we will confirm whether an equivalent fits.

Frequently asked questions
- SKF 24168 ECACK30/C3W33 bearing: what are its dimensions?
- SKF 24168 ECACK30/C3W33 measures 340 mm across the bore and 580 mm across the outside diameter; its width is 243 mm (340 x 580 x 243 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24168.
- What does the K30 suffix mean on an SKF bearing?
- K30 identifies a tapered bore with a 1:30 taper. The bearing then mounts on a tapered shaft seat or with an adapter sleeve, which allows the internal radial clearance to be adjusted. Confirm the shaft taper and set clearance by measurement to avoid mounting damage.
- How do I choose the right internal radial clearance?
- Clearance follows the application and the mounting arrangement. A wider clearance such as C3 suits cases with fit interference, temperature differences or misalignment. Review the operating conditions and the manufacturer's tables, and ask us if you want a second opinion.
- Are SKF spherical roller bearings interchangeable with other brands?
- Often they can be replaced by bearings from other makers that share the same dimensions and suffix designation. Tolerances, radial clearance and load rating may not be identical, so check the main dimensions and the working conditions. Send us the part number and we will help locate the equivalent.
