How to read SKF 2205 ETN9/W64
- 22Series
- Self-aligning ball bearings, 22 series. For the same bore, each series has a different outside diameter and width.
- 05Bore
- 25 mm bore: 05 × 5.
- ETN9/W64Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
2205 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 2205 ETN9/W64 bearing has a 25 mm bore, a 52 mm outside diameter and a 18 mm width (25 x 52 x 18 mm).

SKF self-aligning ball bearings from the ETN/W series are double-row ball bearings with a spherical outer raceway, which allows them to compensate for angular misalignment between shaft and housing. They are used in equipment where shaft deflection or mounting errors generate moderate radial and axial loads. MR Accesorios Industriales carries this line as a brand and advises you on choosing the correct code for your application.
The designation of these bearings combines the basic number with suffixes that indicate design characteristics. For example, in 1211 ETN9/W64, the 1211 defines the size and series; ETN9 indicates a glass fiber reinforced polyamide cage and an optimized internal design; W64 indicates a special treatment for particular temperature or lubrication conditions. In 2205 ETN9/W64 and 2208 ETN9/W64 the same scheme is repeated: basic number, cage suffix and special execution suffix. Knowing these codes allows you to order the exact replacement without confusion.
These bearings are used in industrial fans, centrifugal pumps, conveyors, textile machines, bottling equipment and mixers, among others. In Argentina, they are common in the food, chemical and process industries, where shafts often have deflections or supports are not perfectly aligned. Their self-aligning capability reduces the risk of premature failures and simplifies maintenance in plants that operate continuously.
To select the appropriate bearing, take into account the radial and axial load, rotation speed and environmental conditions. The sealing or protective plates must be chosen according to the presence of dust, moisture or liquids. Lubrication can be grease or oil; respect the recommended quantity and type. During mounting, avoid striking the raceway and verify the initial shaft alignment. Excessive misalignment, even if the bearing compensates for it, shortens its service life.
Regarding equivalents, self-aligning bearings from different brands can be interchanged if the main dimensions, internal clearance and cage execution match. Do not rely only on the basic number: the suffixes change the behavior. If your equipment has an SKF code, the safest option is to replace it with an identical one or one with equivalent performance. MR Accesorios Industriales can help you interpret the designation and find the appropriate alternative.
If you need to replace an SKF self-aligning ball bearing from the ETN/W series, send us the complete code via WhatsApp. At MR Accesorios Industriales we will request a quote and guide you so that the choice is correct. Let's not improvise with the replacement: the exact code prevents downtime and major damage.

Frequently Asked Questions
- What are the dimensions of the SKF 2205 ETN9/W64 bearing?
- The SKF 2205 ETN9/W64 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 ETN9 suffix mean in an SKF bearing?
- The ETN9 suffix indicates that the bearing has a glass fiber reinforced polyamide cage and an optimized internal design. This cage reduces weight and improves high-speed behavior, as well as better resisting friction.
- Can I replace an SKF self-aligning ball bearing with another brand?
- Yes, as long as the main dimensions, internal clearance and cage type match. The basic number alone is not enough: the suffixes define characteristics that affect performance. Consult us with the complete code to verify the equivalence.
- How is a self-aligning ball bearing mounted to avoid failures?
- Mount with appropriate tools, without striking the raceway. Verify the shaft and housing alignment, and apply the recommended lubrication. Although the bearing compensates for misalignment, careful mounting extends its service life.
