SKF EKTN series self-aligning ball bearings are ball bearings with a spherical outer ring and two rows of balls, which allows them to self-align and compensate for angular misalignment between shaft and housing. They are used in applications where the shaft may flex or where mounting is not perfectly parallel, such as fans, conveyors or agricultural machinery. MR Accesorios Industriales sells this line as an official brand, with technical advice to choose the correct size.

The designation of these bearings follows the SKF scheme: the basic number (for example, 1205, 1206, 1207) indicates the series and size; the letter E indicates an internally optimized design; KTN9 corresponds to the glass fiber reinforced polyamide cage, suitable for moderate temperatures; and the suffix /C3 indicates a larger internal radial clearance than standard, useful when there are tight fits or thermal differences between shaft and housing. Thus, a 1205 EKTN9/C3 combines size, cage and clearance according to the application.

These bearings are found in equipment where alignment is not perfect: industrial fans, dryers, belt conveyors, food industry machines, mixers and agricultural equipment. In Argentina, they are commonly seen in food plants, cement plants and maintenance workshops looking for a simple solution for shafts that become misaligned due to flexing or mounting. Their self-aligning capability reduces the risk of premature failures and simplifies mounting.

To select correctly, take into account radial and axial load, rotation speed and environmental conditions. Sealing is key: if there is dust or moisture, consider variants with seals or shields. Lubrication must be suitable for the temperature and speed; in many cases, lithium grease is sufficient, but check compatibility. C3 clearance is recommended when the fit is tight or there are thermal gradients. During mounting, ensure reasonable initial alignment and avoid impacts that damage the raceways.

As for equivalents, SKF self-aligning ball bearings can be interchanged with those of other brands that follow the same basic designation, such as FAG, NSK or NTN, but always check tolerances and internal clearance, as they may vary. Do not invent codes: if you need to replace a bearing, compare the main dimensions (bore, outer diameter and width) and operating conditions. MR Accesorios Industriales can help you find the right replacement within its product line.

If you already have the code for your SKF self-aligning ball bearing, send it by WhatsApp to MR Accesorios Industriales and we will quote the exact size. We can also advise you if you need a sealed variant or a different clearance. With more than 80 years in the market, MR is your partner for bearings and power transmission.
