Decoding SKF C 3224 K/C3
- C 32Series
- CARB roller bearings, C 32 series. Series differ in outside diameter and width even when the bore is the same.
- 24Bore
- Bore 120 mm (24 × 5).
- K/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
C 3224 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF C 3224 K/C3 measures 120 mm across the bore and 215 mm across the outside diameter; its width is 76 mm (120 x 215 x 76 mm).

For equipment where radial space is tight and shafts flex, SKF CARB toroidal roller bearings offer a self-aligning, single-row radial solution with a reduced cross section. They handle high radial loads together with small axial loads in both directions, and they tolerate angular misalignment. Gearboxes, pumps and industrial fans are typical examples of where this combination matters.
Reading a CARB designation is straightforward. The C stands for the CARB bearing type, and the number that follows gives the size. A K suffix means the bore is tapered at 1:12, so the bearing can go onto a tapered shaft or an adapter sleeve. Clearance is shown by a suffix such as /C3 or /C4: C3 is wider than standard, and C4 wider still. So C 2215 K/C3 is a CARB bearing with tapered bore and C3 clearance, while C 2226 K/C4 carries C4 clearance for fits or temperatures that call for more internal room.
These bearings show up in cement, mining, steel, paper and food processing plants. Common equipment includes speed reducers, mills, conveyor belts, centrifugal pumps and industrial fans. Because they self-align, they suit long shafts or shafts that deflect, where perfect alignment is not realistic. They also fit where high radial capacity is needed but axial space is limited.
Selection starts with the radial and axial loads, then rotation speed, operating temperature and lubrication method, grease or oil. With a tapered bore, check radial clearance after tightening, because mounting on a taper reduces it. Alignment and proper sealing keep contamination out. Use the lubricant specified for the bearing and renew it at the recommended interval.
On interchangeability, SKF CARB bearings can be replaced by bearings from other brands that use the same international designation, but always confirm dimensions and tolerances against the original. MR Industrial Accessories LLC supplies SKF bearings as one of the brands in its range. When replacing an existing bearing, compare the full code and the operating conditions, not just the code.

Frequently asked questions
- SKF C 3224 K/C3 bearing: what are its dimensions?
- SKF C 3224 K/C3 measures 120 mm across the bore and 215 mm across the outside diameter; its width is 76 mm (120 x 215 x 76 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation C 3224.
- What does the K suffix mean on a CARB bearing?
- K indicates a tapered bore with a 1:12 taper. This lets the bearing be mounted on a tapered shaft or with an adapter sleeve, which makes it easier to adjust internal radial clearance.
- How do C3 and C4 clearance differ?
- C3 internal radial clearance is larger than standard, and C4 is larger than C3. They are selected when high temperatures or mounting fits require extra clearance to absorb expansion.
- Where are SKF CARB bearings used?
- They are found in applications with high radial loads and misalignment, such as gearboxes, pumps, fans, mills and conveyors. Their compact design suits reduced axial spaces.
