Decoding SKF 2206 EKTN9/C3
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- EKTN9/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2206 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF EKTN series self-aligning ball bearings feature a spherical outer ring and two rows of balls, so they accommodate angular misalignment between shaft and housing. Maintenance teams use them where shafts flex or mounting is not perfectly parallel, such as in fans, conveyors and agricultural machinery. MR Industrial Accessories LLC supplies this line and helps you match the right size to your application.
Reading the designation helps you order correctly. The basic number, such as 1205, 1206 or 1207, sets the series and size. The letter E marks an internally optimized design. KTN9 identifies the glass fiber reinforced polyamide cage for moderate temperatures. The suffix /C3 calls out greater internal radial clearance than standard, which is useful with tight fits or when shaft and housing see different temperatures. A 1205 EKTN9/C3 therefore combines size, cage and clearance for the job.
You will find these bearings in equipment where alignment is not perfect: industrial fans, dryers, belt conveyors, food industry machines, mixers and agricultural equipment. In food plants, cement plants and maintenance workshops, they offer a straightforward way to handle shafts that go out of line from flexing or mounting. Their self-aligning capability lowers the risk of premature failure and makes installation simpler.
Selection depends on radial and axial load, rotation speed and the environment. Sealing matters: in dusty or damp conditions, look at sealed or shielded variants. Lubrication must suit the temperature and speed; lithium grease often works, but confirm compatibility. Choose C3 clearance when fits are tight or thermal gradients exist. During mounting, keep initial alignment reasonable and avoid impacts that can damage the raceways.
SKF self-aligning ball bearings can be interchanged with other brands that use the same basic designation, including FAG, NSK and NTN, but always check tolerances and internal clearance because they can differ. MR Industrial Accessories LLC can help you find the right replacement from its product range.

Frequently asked questions
- SKF 2206 EKTN9/C3 bearing: what are its dimensions?
- SKF 2206 EKTN9/C3 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 20 mm (30 x 62 x 20 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2206.
- What does the C3 suffix mean in an SKF self-aligning ball bearing?
- C3 indicates greater internal radial clearance than standard. It suits tight fits, thermal differences between shaft and housing, or cases where deformation must be compensated. It is a controlled additional play, not an excessive clearance.
- Do these bearings come with seals?
- The EKTN series mentioned here is normally supplied open, without seals. If your application needs protection from dust or moisture, ask about sealed or shielded variants, or consider external oil seals.
- Can I replace an SKF self-aligning ball bearing with one from another brand?
- Yes, provided the main dimensions and internal clearance match. Brands such as FAG, NSK or NTN have equivalents, but verify tolerances and the suffix. If in doubt, send us the part number and we will advise.
