How to read SKF 2201 ETN9
- 22Series
- Self-aligning ball bearings, 22 series. For the same bore, each series has a different outside diameter and width.
- 01Bore
- 12 mm bore: code 01 stands for 12 mm by standard.
- ETN9Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
2201 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF self-aligning ball bearings from the ETN9 series are double-row ball bearings with a spherical raceway in the outer ring, allowing them to compensate for angular misalignment between shaft and housing. They are used in applications where perfect alignment cannot be guaranteed, such as belt drives, fans or agricultural machinery. MR Accesorios Industriales carries this series as part of its SKF bearing line.
The designation of these bearings follows the SKF scheme: the basic number (for example, 1200, 1201, 1202, etc.) indicates size and load capacity. The suffix ETN9 identifies a glass fiber reinforced polyamide cage, suitable for moderate operating temperatures and high speeds. In the examples 1200 ETN9 through 1207 ETN9, the first digit '1' indicates the diameter series, and the next two digits the size code. Knowing this nomenclature allows you to order the exact replacement.
These bearings are used in equipment where shaft flexing or unavoidable misalignment occurs: belt and chain drives, industrial fans, centrifugal pumps, textile machines, agricultural equipment and conveyors. In Argentina, they are common in the food, cement and agricultural sectors, where dust and moisture demand robust bearings. Their self-aligning capability reduces wear and extends the service life of the assembly.
To select the right bearing, consider radial and axial load, rotational speed and environmental conditions. Sealing is key: if there is dust or moisture, choose variants with seals or protective shields. Lubrication must be suitable for the temperature and speed; in many cases, these bearings come pre-lubricated from the factory. During assembly, ensure correct initial alignment and avoid impacts that could damage the rings or balls. The ETN9 cage requires no additional maintenance.
Regarding equivalents, SKF self-aligning ball bearings can be interchanged with those from other brands that follow the same dimensional designation, such as FAG, NSK or NTN, provided the dimensions and cage suffix match. However, not all suffixes are equivalent: SKF's ETN9 may have its counterpart in other nomenclatures. For a safe replacement, verify the critical dimensions and consult a specialist. MR Accesorios Industriales can advise you on the selection.

Frequently Asked Questions
- What are the dimensions of the SKF 2201 ETN9 bearing?
- The SKF 2201 ETN9 bearing has a 12 mm bore, a 32 mm outside diameter and a 14 mm width (12 x 32 x 14 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2201.
- What does the ETN9 suffix mean on an SKF bearing?
- The ETN9 suffix indicates the bearing has a glass fiber reinforced polyamide cage, designed for high-speed applications and moderate temperatures. This cage is lightweight and resistant, and requires no additional lubrication.
- When should I use a self-aligning ball bearing instead of a deep groove ball bearing?
- When there is misalignment between shaft and housing, whether due to shaft flexing, imperfect mounting or structure settling. The self-aligning bearing compensates for that misalignment and prevents parasitic loads that would reduce service life.
- How do I order an SKF ETN9 self-aligning ball bearing at MR?
- Send the full part number via WhatsApp, for example 1205 ETN9, and we'll quote you. If you're not sure of the part number, send us the shaft and housing dimensions, and we'll help you identify it.
