Decoding SKF 23144 CCK/HA3C4W33
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 44Bore
- Bore 220 mm (44 × 5).
- CCK/HA3C4W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23144 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23144 CCK/HA3C4W33 measures 220 mm across the bore and 370 mm across the outside diameter; its width is 120 mm (220 x 370 x 120 mm).

SKF spherical roller bearings are self-aligning units that use two rows of rollers to handle heavy radial loads along with axial loads in both directions, even when the shaft and housing are misaligned. Equipment such as conveyors, mills, centrifugal pumps, and gearboxes often relies on them where shaft deflection or mounting inaccuracies occur. MR Industrial Accessories supplies this SKF line and offers technical support to help you choose the right variant.
The part number encodes construction details. In 23040 CCK/HA3C4W33, the digits give the size and dimension series; CC is the internal design with symmetrical rollers and a stamped steel cage; K means a tapered bore (1:12); HA3 relates to ring surface treatment or special material; C4 sets radial internal clearance above normal; W33 indicates a lubrication groove and holes in the outer ring. Other sizes like 23052 CCK/HA3C4W33 or 23148 CCK/HA3C4W33 follow the same pattern, with only the size and some suffixes changing.
You will find these bearings in continuous-process industries where uptime matters: cement, mining, steel, paper, food, and aggregate processing. Typical applications include ball mills, jaw crushers, vibrating screens, industrial fans, slurry pumps, and chain conveyors. Their self-aligning capability suits long shafts or supports that flex under load, helping to avoid premature failure from misalignment.
When selecting, consider radial and axial loads, speed, and the operating environment. A K suffix requires a tapered shaft or adapter sleeve, which simplifies setting radial clearance. C4 clearance fits situations with large temperature differences between inner and outer rings. Lubrication may be grease or oil; with W33, confirm that the lubrication paths line up with your system. Proper initial alignment and effective sealing are essential to keep contaminants out.
SKF spherical roller bearings can be interchanged with equivalent designs from other brands that use the same dimensions and suffix system, such as FAG, NSK, NTN, or Timken. Always check tolerances, internal clearance, and lubrication conditions, since small internal differences can affect performance.

Frequently asked questions
- SKF 23144 CCK/HA3C4W33 bearing: what are its dimensions?
- SKF 23144 CCK/HA3C4W33 measures 220 mm across the bore and 370 mm across the outside diameter; its width is 120 mm (220 x 370 x 120 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23144.
- What does the K suffix indicate?
- K denotes a tapered bore with 1:12 taper. This allows mounting on a tapered shaft or adapter sleeve, making it easier to adjust internal radial clearance during installation.
- When should I select C4 radial clearance?
- C4 is greater than normal clearance and is advisable when there are significant temperature differences between inner and outer rings, at high speeds, or when expansion must be compensated.
- How do I know if I need the W33 variant?
- W33 means the outer ring has a groove and three lubrication holes. It is helpful when lubricating through the housing. If you use oil bath or grease from the shaft, it may not be required.
