How to read SKF 23944 CCK/W33
- 239Series
- Spherical roller bearings, 239 series. For the same bore, each series has a different outside diameter and width.
- 44Bore
- 220 mm bore: 44 × 5.
- CCK/W33Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
23944 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 23944 CCK/W33 bearing has a 220 mm bore, a 300 mm outside diameter and a 60 mm width (220 x 300 x 60 mm).

The SKF spherical roller bearing is a self-aligning, double-row component designed to withstand high radial loads and axial loads in both directions. Its spherical outer raceway allows the shaft to misalign without losing functionality, which simplifies mounting and absorbs alignment errors. It is used in applications where shaft deflection or foundation settling are unavoidable. MR Accesorios Industriales supplies this line with technical advice to select the right variant.
The designation of this series is read in blocks: the base number identifies the size, and the suffixes indicate design features. For example, in 22228 CCK/W33, the prefix 222 corresponds to the medium-section spherical roller series; CC means it incorporates two guide ribs and a central ring, which improves roller guidance; K indicates the tapered bore (taper 1:12); and W33 indicates that the outer ring has a groove and three holes for lubrication. Other examples such as 22230 CCK/W33 or 22244 CCK/W33 share the same structure, varying only in size. Knowing these suffixes is key to ordering the correct replacement.
These bearings are used in equipment subjected to heavy loads and misalignment, such as conveyor belts, mills, crushers, centrifugal pumps, industrial fans and paper machines. In Argentina, they are common in the cement, mining, steel and food processing industries. Their ability to withstand combined loads and operate with deflected shafts makes them ideal for assemblies where perfect alignment between supports cannot be guaranteed. They are also used in large gearboxes and gear reducers.
To select correctly, take into account the radial and axial load, the rotational speed and the type of lubrication. The tapered bore (suffix K) allows mounting with an adapter sleeve, which facilitates adjustment and disassembly. Sealing is critical: if the environment has dust or moisture, it is recommended to choose variants with additional seals or protectors. Lubrication can be with grease or oil; in the latter case, the W33 groove and holes facilitate lubricant renewal. Initial alignment must be careful, although the bearing allows subsequent misalignment.
When looking for equivalents, each manufacturer has its own designations, but standardized suffixes (such as K for taper or W33 for lubrication groove) are maintained across many brands. This allows bearings to be interchanged between different origins if dimensions and load capacities are respected. Always verify the complete part number and tolerances before replacing one bearing with another brand. MR Accesorios Industriales supplies the SKF brand and can advise you on interchangeability.
If you need an SKF spherical roller bearing, the fastest way is to send us the complete part number by WhatsApp. With that information, our technical team identifies the exact variant and sends you the quote. We work with the main sizes and can source those we do not have in our warehouse. MR Accesorios Industriales advises you so you order the correct bearing.

Frequently Asked Questions
- What are the dimensions of the SKF 23944 CCK/W33 bearing?
- The SKF 23944 CCK/W33 bearing has a 220 mm bore, a 300 mm outside diameter and a 60 mm width (220 x 300 x 60 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 23944.
- What does the suffix K mean in an SKF bearing?
- The suffix K indicates that the bearing has a tapered bore with 1:12 taper. This allows it to be mounted on a tapered shaft or with an adapter sleeve, which facilitates adjustment and disassembly. It is a widely used option when firm and precise fixation is required.
- What is the purpose of the W33 groove and holes?
- The W33 designation means that the outer ring has a groove and three holes distributed for lubrication. This allows lubricant to be injected directly into the rolling zone, which is useful in applications requiring frequent relubrication or when access is difficult.
- How do I request a quote for a spherical roller bearing?
- Send the complete part number by WhatsApp, for example 22228 CCK/W33. With that information we send you the quote. If you are not sure of the part number, send us a photo or the main dimensions and we will help you identify it.
