Decoding SKF 2208 ETN9/W64
- 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).
- ETN9/W64Suffix
- 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 ETN9/W64 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 self-aligning ball bearings in the ETN/W series are double-row bearings with a spherical outer raceway. This design lets them handle angular misalignment between shaft and housing, making them suitable for equipment where shaft deflection or mounting errors produce moderate radial and axial loads. MR Industrial Accessories LLC supplies this line and helps you match the right code to your application.
The part number tells you the size, cage and special execution. Take 1211 ETN9/W64: 1211 is the basic size and series; ETN9 means a glass fiber reinforced polyamide cage with optimized internal design; W64 is a special treatment for particular temperature or lubrication conditions. The same pattern applies to 2205 ETN9/W64 and 2208 ETN9/W64. Reading these suffixes correctly lets you order the exact replacement.
Typical uses include industrial fans, centrifugal pumps, conveyors, textile machines, bottling equipment and mixers. In food, chemical and process plants, shafts often deflect or supports are not perfectly aligned. The self-aligning feature lowers the risk of premature failure and simplifies maintenance in continuous operations.
When selecting, consider radial and axial load, speed and the environment. Choose seals or shields based on dust, moisture or liquids. Grease or oil lubrication is possible; follow the recommended type and quantity. During mounting, do not strike the raceway and check initial shaft alignment. Even though the bearing compensates for misalignment, excessive misalignment shortens service life.
Equivalents across brands can be interchanged if the main dimensions, internal clearance and cage execution match. Do not rely on the basic number alone: suffixes change behavior. If your equipment carries an SKF code, the safest choice is an identical bearing or one with equivalent performance. MR Industrial Accessories LLC can help you interpret the designation and find a suitable alternative.

Frequently asked questions
- SKF 2208 ETN9/W64 bearing: what are its dimensions?
- SKF 2208 ETN9/W64 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 ETN9 suffix mean in an SKF bearing?
- ETN9 indicates a glass fiber reinforced polyamide cage and an optimized internal design. This cage reduces weight, improves high-speed behavior and better resists friction.
- Can I replace an SKF self-aligning ball bearing with another brand?
- Yes, if the main dimensions, internal clearance and cage type match. The basic number alone is not enough because suffixes affect performance. Share the complete code with us to verify equivalence.
- How should a self-aligning ball bearing be mounted to avoid failures?
- Use appropriate tools and do not strike the raceway. Check shaft and housing alignment, and apply the recommended lubrication. Although the bearing compensates for misalignment, careful mounting extends service life.
