Decoding SKF 6205 ETN9
- 62Series
- Deep groove ball bearings, 62 series. Series differ in outside diameter and width even when the bore is the same.
- 05Bore
- Bore 25 mm (05 × 5).
- ETN9Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6205 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6205 ETN9 measures 25 mm across the bore and 52 mm across the outside diameter; its width is 15 mm (25 x 52 x 15 mm).

The SKF ETN9 deep groove ball bearing is a single row bearing that uses a glass fiber reinforced polyamide cage. It handles moderate radial and axial loads in both directions and is common in electric motors, pumps, fans, and transmissions. The self-lubricating cage supports high-speed operation and low maintenance.
The ETN9 suffix identifies a ball-centered cage made of glass fiber reinforced polyamide. It does not change the bearing's principal dimensions; it defines the cage material and design, which affect limiting speed and operating temperature. Examples include 6204 ETN9, 6205 ETN9, and 6206 ETN9, all single row bearings of the 62 series with a medium section.
These bearings appear in automotive, food, chemical, and metallurgical plants. Typical equipment includes low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts, and machine tools. The design works in fixed arrangements and where small axial adjustment is needed.
When selecting an ETN9 bearing, review the radial and axial loads, rotational speed, and environmental conditions. The polyamide cage resists fatigue and permits higher speeds than steel cages, but continuous operating temperature must not exceed 120 °C. During mounting, align shaft and housing correctly and use the recommended fitting methods to avoid damaging rings or balls.
Lubrication: bearings usually arrive with a standard grease fill, though some applications need additional lubrication. Sealing is also important. In dusty, moist, or particle-laden environments, choose bearings with seals or protective shields. Interchangeability between brands is possible when standardized dimensions and tolerances are respected, but always check the manufacturer's specifications.

Frequently asked questions
- SKF 6205 ETN9 bearing: what are its dimensions?
- SKF 6205 ETN9 measures 25 mm across the bore and 52 mm across the outside diameter; its width is 15 mm (25 x 52 x 15 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6205.
- What does the ETN9 suffix mean in an SKF bearing?
- The ETN9 suffix indicates a ball-centered cage made of glass fiber reinforced polyamide. This design allows higher speeds and lower weight compared to steel cages.
- What is the maximum operating temperature for a bearing with an ETN9 cage?
- The reinforced polyamide cage withstands continuous temperatures up to 120 °C. For higher temperatures, inquire about other designs with a metal cage.
- Can I replace an SKF ETN9 bearing with another brand?
- Yes, as long as dimensions and tolerances match the standard. Verify the alternative manufacturer's specifications to ensure compatibility and expected performance.
