- 05Bore
- 25 mm bore: 05 × 5.
- E-2RS1KTN9/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).

SKF series 22 self-aligning ball bearings are double-row ball bearings with a spherical outer ring, which allows them to align automatically and compensate for angular misalignment between shaft and housing. They are used in equipment where perfect alignment cannot be guaranteed, such as conveyors, fans or agricultural machinery. MR Accesorios Industriales carries this SKF line, a brand we sell.
The designation of these bearings is read in parts. The base number, such as 2205, 2206 or 2213, indicates the series and size: the first two digits indicate series 22 and the next two the bore diameter. The E suffix indicates an optimized internal design. Then, 2RS1 means they have rubber seals on both sides, K indicates tapered bore (1:12), TN9 polyamide cage and /C3 an internal radial clearance greater than normal. Thus, a 2205 E-2RS1KTN9/C3 is a sealed self-aligning ball bearing with tapered bore and C3 clearance.
These bearings are used in equipment where there is shaft deflection or alignment difficulties. They are common in belt conveyors, industrial fans, mixers, agricultural machinery, pumps and compressors. In Argentina, you'll find them in food plants, cement plants, tanneries and metalworking shops. Their self-aligning capability reduces wear and extends service life under demanding mounting conditions.
To select correctly, take into account the load, speed and environment. The 2RS1 seal protects against dust and moisture, ideal for dirty environments. The K tapered bore is mounted on shafts with 1:12 taper or with an adapter sleeve, which facilitates mounting and dismounting. C3 clearance is recommended when there are high temperatures or interference fits. Factory lubrication is usually sufficient, but in severe applications it may require relubrication. Check the initial alignment to take advantage of the self-aligning capability.
As for equivalences, SKF self-aligning ball bearings can be interchanged with those of other brands that follow the same international designation. For example, a 2205 E-2RS1KTN9/C3 is equivalent to a bearing with the same characteristics from another company. Always confirm the tolerances and radial clearance, as they may vary between manufacturers. MR Accesorios Industriales carries SKF as a brand, and also offers alternatives from other brands to suit your needs.

Frequently Asked Questions
- What are the dimensions of the SKF 2205 E-2RS1KTN9/C3 bearing?
- The SKF 2205 E-2RS1KTN9/C3 bearing has a 25 mm bore, a 52 mm outside diameter and a 18 mm width (25 x 52 x 18 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2205.
- What does the K suffix mean in an SKF self-aligning ball bearing?
- The letter K indicates that the bearing has a tapered bore with 1:12 taper. This allows it to be mounted on tapered shafts or with adapter sleeves, facilitating adjustment and dismounting.
- What is the C3 clearance for in these bearings?
- C3 radial clearance is greater than normal. It is used when there are high temperatures or interference fits, to prevent the bearing from becoming preloaded and failing prematurely.
- How do I request a quote for SKF self-aligning ball bearings?
- Send the full part number by WhatsApp to MR Accesorios Industriales. We'll quote you promptly and advise you so you can choose the right option for your equipment.
