How to read SKF 6205 ETN9/C4
- 62Series
- Deep groove ball bearings, 62 series. For the same bore, each series has a different outside diameter and width.
- 05Bore
- 25 mm bore: 05 × 5.
- ETN9/C4Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6205 is the standard (ISO) basic designation: it defines the type, the series and the bore.

The SKF ETN9/C series deep groove ball bearing is a precision component designed to carry radial and axial loads in both directions. Its construction with a polyamide cage and specially graded balls allows high speeds and low friction. It is used in electric motors, pumps, fans and transmissions, where reliability and continuous performance are critical. MR Accesorios Industriales sells this brand for the Argentine market.
The ETN9/C designation is interpreted as follows: ETN9 indicates a design with a glass fiber reinforced polyamide cage, suitable for high speeds and moderate temperatures; C followed by a number (C3, C4) defines the internal radial clearance. For example, 6203 ETN9/C4 has a radial clearance greater than standard, ideal for applications with interference fits or thermal differences between shaft and housing. 6205 ETN9/C3 and 6205 ETN9/C4 share the same bore and outside diameter, but differ in internal clearance according to the requirement.
These bearings are used in low and medium power electric motors, centrifugal pumps, industrial fans, compressors and machine tools. In Argentina, they are common in the automotive, metallurgical, food and petrochemical sectors. Their ability to operate at high speeds with low noise makes them suitable for equipment where predictive maintenance and vibration reduction are a priority.
To select correctly, take the radial clearance into account: C3 for assemblies with a tight fit on the shaft or housing, or when the operating temperature exceeds 100 °C; C4 for more severe conditions. Lubrication must be adequate: high-speed grease for standard applications or oil in circulation systems. Check shaft and housing alignment; although the deep groove ball bearing tolerates small misalignments, a misaligned assembly shortens its service life.
As for equivalences, SKF deep groove ball bearings can be interchanged with those of other brands that follow the same dimensional designation (for example, the 62 series). However, special designs such as ETN9/C do not always have a direct replacement; always verify tolerances and radial clearance before substituting.

Frequently Asked Questions
- What are the dimensions of the SKF 6205 ETN9/C4 bearing?
- The SKF 6205 ETN9/C4 bearing has a 25 mm bore, a 52 mm outside diameter and a 15 mm width (25 x 52 x 15 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6205.
- What does ETN9 mean in an SKF bearing?
- ETN9 indicates a glass fiber reinforced polyamide cage, designed for high speeds and good thermal resistance. It is a common design in deep groove ball bearings for demanding applications.
- What is the difference between C3 and C4?
- C3 and C4 indicate the internal radial clearance. C3 has a clearance greater than standard and C4 is even greater. They are chosen according to the mounting fit and thermal conditions to avoid excessive preload.
- Can I replace an SKF ETN9 with another brand?
- Yes, if the other brand offers a bearing with the same dimensional designation and equivalent radial clearance. Always verify tolerances and the special design, since ETN9 may not have an exact replacement.
