How to read SKF C 2208 KTN9
- C 22Series
- CARB roller bearings, C 22 series. For the same bore, each series has a different outside diameter and width.
- 08Bore
- 40 mm bore: 08 × 5.
- KTN9Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
C 2208 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF CARB rollers series C are self-aligning toroidal roller radial bearings, designed to withstand high radial loads and compensate for misalignment between shaft and housing. Their compact design and load capacity make them ideal for applications where space is limited and robustness is required. At MR Accesorios Industriales we sell this line, with technical advice to select the right part number for your equipment.
The series C designation is interpreted as follows: the letter C identifies the CARB series; the first two digits indicate the size, which varies by part number; the suffixes KTN9 indicate a glass fiber reinforced polyamide cage and a tapered bore. The examples C 2209 KTN9, C 2210 KTN9, C 2211 KTN9, C 2212 KTN9 and C 2213 KTN9 show the size progression. Always verify the complete part number to ensure interchangeability.
These bearings are used in industries such as metallurgy, cement, paper and mining, in transmission equipment, gearboxes, paper machines, industrial fans and conveyors. In Argentina, they are common in processing plants and in large agricultural machinery. Their self-aligning capability makes them useful where shafts undergo flexing or misalignment from mounting, avoiding additional stresses on the bearings and extending the service life of the assembly.
To select correctly, consider the radial load, speed and permissible misalignment. Mounting requires shafts with adequate tolerance and housings that allow axial displacement. Lubrication must be the one recommended by the manufacturer, and it is crucial to maintain initial alignment within the specified limits. Sealing will depend on the environment: in the presence of dust or moisture, choose additional protections. The KTN9 cage allows high speeds and moderate temperatures.
As for equivalents, SKF CARB bearings can be interchanged with products from other brands that follow the same dimensional designation, but always verify tolerances and load capacities. Not all suffixes are equivalent between manufacturers. For replacements, it is essential to compare the complete part number and the operating conditions. At MR Accesorios Industriales we can advise you on the best option available for your specific application.

Frequently Asked Questions
- What are the dimensions of the SKF C 2208 KTN9 bearing?
- The SKF C 2208 KTN9 bearing has a 40 mm bore, a 80 mm outside diameter and a 23 mm width (40 x 80 x 23 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation C 2208.
- What does the KTN9 suffix mean on an SKF CARB bearing?
- The KTN9 suffix indicates that the bearing has a tapered bore and a glass fiber reinforced polyamide cage. This cage is suitable for high speeds and moderate temperatures, and the tapered bore facilitates mounting on shafts with an adapter sleeve.
- Are SKF CARB series C bearings interchangeable with other brands?
- They can be interchangeable if the main dimensions and design match, but suffixes and tolerances may vary between manufacturers. Always verify the complete part number and the operating conditions before replacing. Ask us about specific equivalents.
- How is an SKF CARB bearing with a tapered bore mounted?
- It is mounted on a tapered shaft or with an adapter sleeve. It is important to follow the manufacturer's instructions for tightening and lubrication. Misalignment must be corrected before start-up to avoid additional loads.
