How to read SKF 23276 CAK/W33
- 232Series
- Spherical roller bearings, 232 series. For the same bore, each series has a different outside diameter and width.
- 76Bore
- 380 mm bore: 76 × 5.
- CAK/W33Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
23276 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF CAK/W series spherical roller bearings are self-aligning, double-row components designed to withstand high radial loads and angular misalignment. Their tapered bore allows precise mounting on shafts with adapter sleeves or directly on tapers. They are used in industrial applications where shaft deflection or misalignment demands reliable, long-lasting self-aligning capability.
The designation of these bearings is interpreted as follows: the base number indicates the dimension series, and the suffixes CAK and W33 provide key information. CAK indicates a design with tapered bore (1:12 taper) and machined brass cage, while W33 indicates the presence of a lubrication groove and holes in the outer ring. For example, in 23084 CAK/W33, the 23084 defines the size, CAK the tapered bore and W33 the lubrication configuration. This nomenclature allows quick identification of mounting and lubrication characteristics.
These bearings are used in industries such as cement, mining, steel, paper and material handling. In Argentina, they are common in large gearboxes, mills, crushers, conveyor belts and continuous process equipment. Their ability to withstand combined loads and misalignment makes them suitable for machinery subject to vibration or shaft deflection, where reliability and long service life are critical.
For correct selection, consider radial and axial load, rotational speed and mounting type. The tapered bore facilitates mounting with an adapter sleeve or directly on a tapered shaft, achieving a precise fit. It is essential to verify initial alignment and use the appropriate internal clearance, which is adjusted during mounting. Lubrication must be as recommended by the manufacturer, and the W33 groove allows relubrication through the outer ring. Careful mounting extends bearing life.
Regarding equivalences, spherical roller bearings with tapered bore and lubrication groove are manufactured under international standards, allowing interchange between different brands as long as dimensions and tolerances match. SKF is a global reference, and its CAK/W33 designations are widely recognized. When looking for a replacement, verify that the code includes the suffix K for tapered bore and W33 for lubrication, and always consult the technical specifications.

Frequently Asked Questions
- What are the dimensions of the SKF 23276 CAK/W33 bearing?
- The SKF 23276 CAK/W33 bearing has a 380 mm bore, a 680 mm outside diameter and a 240 mm width (380 x 680 x 240 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 23276.
- What does the CAK suffix mean in an SKF bearing?
- CAK indicates that the bearing has a tapered bore with 1:12 taper and a machined brass cage. This facilitates mounting on tapered shafts or with adapter sleeves, and the brass cage offers high strength and precise roller guidance.
- What is the W33 groove for?
- W33 indicates that the outer ring has a lubrication groove and holes. This allows relubrication of the bearing through the housing, facilitating maintenance and extending service life in applications with high loads or speeds.
- How do I choose the right bearing for my application?
- Consider radial and axial load, speed, mounting type and environmental conditions. Verify that the code includes K for tapered bore and W33 for lubrication. Consult us with your equipment data and we will advise you without obligation.
