The SKF ETN9 series deep groove ball bearing is a single row bearing with a glass fiber reinforced polyamide cage, designed to withstand moderate radial and axial loads in both directions. It is used in a wide variety of industrial applications requiring high speed and low maintenance, such as electric motors, pumps, fans and transmissions. Its robust construction and self-lubricating capability make it ideal for demanding environments.
The ETN9 designation in SKF bearings indicates a design with a glass fiber reinforced polyamide cage, ball centered. Examples in this series, such as 6204 ETN9, 6205 ETN9 and 6206 ETN9, correspond to single row ball bearings of the 62 series, characterized by their medium section and ability to withstand combined radial and axial loads. The ETN9 suffix does not change the main dimensions, but defines the cage type and material, which influences the limiting speed and operating temperature.
These bearings are used in a wide variety of industries in Argentina, such as automotive, food, chemical and metallurgical. Typical applications include low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. Their versatile design allows them to be used both in fixed arrangements and where a small axial adjustment is required.
To correctly select an ETN9 bearing, take into account the radial and axial load it must withstand, the rotational speed and the environmental conditions. The polyamide cage offers good fatigue resistance and allows higher speeds than steel cages, but it is important to verify the working temperature, as it must not continuously exceed 120 °C. During mounting, ensure proper alignment between shaft and housing, and use the recommended fitting methods to avoid damage to the rings or balls.
Regarding lubrication, these bearings usually come with a standard amount of grease, but specific applications may require additional lubrication. Sealing is another key factor: if the environment contains dust, moisture or particles, it is advisable to choose bearings with seals or protective shields. Interchangeability between brands is possible if standardized dimensions and tolerances are respected, but always verify the manufacturer's specifications to ensure optimal performance.

Frequently Asked Questions
- What are the dimensions of the SKF 6204 ETN9 bearing?
- The SKF 6204 ETN9 bearing has a 20 mm bore, a 47 mm outside diameter and a 14 mm width (20 x 47 x 14 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6204.
- What does the ETN9 suffix mean in an SKF bearing?
- The ETN9 suffix indicates that the bearing has a glass fiber reinforced polyamide cage, ball centered. This allows higher speeds and lower weight compared to steel cages.
- What is the maximum operating temperature for a bearing with ETN9 cage?
- The reinforced polyamide cage withstands temperatures up to 120 °C continuously. For higher temperatures, we recommend inquiring about other designs with metal cage.
- Can I replace an SKF ETN9 bearing with another brand?
- Yes, as long as the dimensions and tolerances match the standard. Verify the alternative manufacturer's specifications to ensure compatibility and expected performance.
