Decoding SKF 2208 E-2RS1KTN9/C3
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- E-2RS1KTN9/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2208 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2208 E-2RS1KTN9/C3 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 23 mm (40 x 80 x 23 mm).

SKF series 22 self-aligning ball bearings are double-row bearings with a spherical outer ring. This design lets the bearing adjust itself when the shaft and housing are not perfectly aligned. They are found in equipment such as conveyors, fans, and agricultural machinery. MR Industrial Accessories supplies this SKF line.
The part number tells you what you are getting. The base number, like 2205, 2206, or 2213, shows the series and size: the first two digits are series 22, and the last two give the bore diameter. The E suffix means the internal design is optimized. Then 2RS1 indicates rubber seals on both sides, K means a tapered bore (1:12), TN9 is a polyamide cage, and /C3 is radial internal clearance greater than normal. So a 2205 E-2RS1KTN9/C3 is a sealed self-aligning ball bearing with tapered bore and C3 clearance.
These bearings handle shaft deflection and mounting misalignment. They appear in belt conveyors, industrial fans, mixers, agricultural machinery, pumps, and compressors. Their self-aligning ability reduces wear and helps the bearing last longer when alignment is not perfect.
When selecting, consider load, speed, and environment. The 2RS1 seal keeps out dust and moisture, which suits dirty conditions. The K tapered bore mounts on a 1:12 tapered shaft or with an adapter sleeve, making installation and removal easier. C3 clearance is recommended for high temperatures or interference fits. Factory lubrication is usually enough, but severe applications may need relubrication. Check initial alignment to get the full benefit of self-aligning.
For equivalents, SKF self-aligning ball bearings interchange with other brands that use the same international designation. For example, a 2205 E-2RS1KTN9/C3 matches a bearing with the same features from another maker. Always confirm tolerances and radial clearance, as they can differ between manufacturers. MR Industrial Accessories supplies SKF and also offers alternatives from other brands.

Frequently asked questions
- SKF 2208 E-2RS1KTN9/C3 bearing: what are its dimensions?
- SKF 2208 E-2RS1KTN9/C3 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 23 mm (40 x 80 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2208.
- What does the K suffix mean in an SKF self-aligning ball bearing?
- The K indicates a tapered bore with 1:12 taper. This allows mounting on tapered shafts or with adapter sleeves, which simplifies adjustment and dismounting.
- What is the C3 clearance for in these bearings?
- C3 radial clearance is greater than normal. It is used with high temperatures or interference fits to avoid preloading and premature failure.
- How do I request a quote for SKF self-aligning ball bearings?
- Send the full part number by WhatsApp to MR Industrial Accessories. We will quote promptly and help you select the right option for your equipment.
