Decoding SKF 239/1060 CAKF/C3W33
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- /1060Bore
- Bore: 1060 mm.
- CAKF/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
239/1060 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF spherical roller bearings are double-row, self-aligning units built to carry heavy radial loads together with axial loads in either direction, even when the shaft is not perfectly aligned. The spherical outer raceway lets the bearing adjust on its own, so small mounting errors or shaft deflection do not cause problems. They suit heavy equipment where high load capacity and ruggedness matter more than extreme rigidity. MR Industrial Accessories supplies this line and helps customers choose the right execution.
The suffix string in this series tells you how the bearing is built. Take 239/1060 CAKF/C3W33 and 239/1180 CAKF/C3W33: the 239 prefix is a spherical roller bearing series with a notably slim cross section. CA refers to the cage and roller guidance design, and K means a tapered bore. The F points to an execution with particular manufacturing characteristics. C3 sets internal radial clearance above normal, while W33 means the outer ring has a lubrication groove and holes. Reading these codes correctly tells you how the bearing will behave in service.
These bearings appear in plants where loads are heavy and conditions are harsh: cement mills, aggregate crushers, paper machines, high-flow industrial fans, mining conveyor belts and earthmoving equipment. Large gearboxes and rotary kiln rollers also use them. Because they self-align, they fit long shafts that deflect or assemblies where the supports cannot be lined up precisely. In plants running continuously, that robustness helps avoid unplanned stops caused by early failure.
Selection depends on the radial and axial load the bearing will see, plus rotation speed and the surrounding environment. A K bore needs a suitable adapter sleeve, and mounting must set the correct radial clearance, here C3, which is greater than standard. Lubrication matters just as much: the W33 groove and holes make relubrication easier, but the lubricant still has to match temperature and contamination levels. Initial alignment does not have to be perfect thanks to the self-aligning design, yet leaving excessive permanent misalignment can shorten service life. Check clearance again after mounting.
Spherical roller bearings follow international dimension standards, so a code from another brand with the same basic designation usually interchanges on main dimensions. Internal suffixes, however, can differ between makers: a C3 from one brand may not match another's radial clearance exactly, and the same goes for cage designs. When replacing a bearing, do not stop at the series number; review the operating conditions and ask a specialist. MR Industrial Accessories can explain the differences.

Frequently asked questions
- SKF 239/1060 CAKF/C3W33 bearing: what are its dimensions?
- SKF 239/1060 CAKF/C3W33 measures 1060 mm across the bore and 1400 mm across the outside diameter; its width is 250 mm (1060 x 1400 x 250 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 239/1060.
- What does the C3 suffix mean in a spherical roller bearing?
- C3 means internal radial clearance is greater than normal. It is chosen when the bearing runs at elevated temperatures or with mounting fits that reduce clearance, so excessive preload is avoided and lubrication can work properly.
- How is a bearing with a tapered bore K mounted?
- It goes on an adapter sleeve or a tapered shaft. Radial clearance must be controlled while tightening, because over-tightening cuts clearance and can damage the raceways. Follow the manufacturer's instructions and check with feeler gauges.
- What advantages does the W33 groove and holes offer?
- W33 means the outer ring has a groove and three lubrication holes. Relubrication becomes easier and more even, which helps the bearing last longer in high-load or contaminated applications.
