Decoding SKF C 2210 KTN9/C3
- C 22Series
- CARB roller bearings, C 22 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- KTN9/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
C 2210 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF C 2210 KTN9/C3 measures 50 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (50 x 90 x 23 mm).

For shafts that flex or where alignment between shaft and housing is never perfect, SKF CARB bearings offer a self-aligning solution that still carries high radial loads. The C KTN9/C3 versions combine a toroidal roller design with a tapered bore, a polyamide cage and extra internal clearance. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.
Reading a code such as C 2210 KTN9/C3, C 2211 KTN9/C3 or C 2212 KTN9/C3 helps you confirm what you need. The C marks the CARB family of articulated toroidal rollers. The four digits give the section size. Then K means the bore is tapered, TN9 identifies a reinforced polyamide cage, and C3 signals greater internal radial clearance than standard. That extra clearance is useful when fits are tight on the shaft or when temperature differences exist across the bearing.
These bearings suit equipment where shaft deflection is normal or alignment is hard to maintain: belt conveyors, paper machines, mining machinery, mills, high-flow pumps and industrial fans. In cement, food, chemical and aggregate processing, they often replace a deep groove ball bearing that would otherwise be overloaded by misalignment.
When selecting a size, begin with the radial load and speed, then check that the bearing's permissible misalignment covers what your arrangement will see. The TN9 cage is light and resists fatigue, but confirm it is compatible with your operating temperature and lubricant. A K tapered bore mounts on a tapered shaft or with an adapter sleeve; after tightening, measure the remaining clearance.
Lubrication and sealing have a major effect on how long the bearing lasts. These units accept grease or oil, and in dusty or damp locations you should add external seals or pick a protected variant. Verify initial alignment and the C3 clearance using the correct method: with a tapered seat, clearance is set by axial displacement. Poor mounting practice removes the benefits of the self-aligning design.
CARB is an SKF designation. Other makers may offer articulated bearings with a similar idea, but dimensions and load ratings are not always the same. Before substituting, compare bore diameter, outside diameter, width and permissible load. If you can read the code on the bearing, send it by WhatsApp or email to MR Industrial Accessories LLC and we will quote that exact reference and suggest equivalents if needed.

Frequently asked questions
- SKF C 2210 KTN9/C3 bearing: what are its dimensions?
- SKF C 2210 KTN9/C3 measures 50 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (50 x 90 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation C 2210.
- What does the KTN9/C3 suffix mean on a CARB bearing?
- K stands for tapered bore, TN9 for a polyamide cage, and C3 for increased internal radial clearance. That larger clearance is chosen when interference fits or temperature differences between shaft and housing are present. Always check the full code before asking for a quote.
- How is a CARB bearing with tapered bore mounted?
- It goes on a tapered shaft or an adapter sleeve. You push the bearing axially until the specified residual clearance is reached. Use feeler gauges or a dial indicator to confirm, and do not hit the cage while mounting.
- Can I replace an SKF CARB with another brand?
- Not always directly. CARB is an SKF design; other brands may have similar articulated bearings, but dimensions or capacities can differ. Compare bore diameter, outside diameter, width and permissible load, and consult us with the original code before deciding.
