The SKF deep groove ball bearing from the TN9/C4HLHT series is a single-row bearing with a polyamide cage and C4 internal clearance, designed to work at high temperatures. It is used in applications where there is thermal expansion and a clearance greater than standard is required, such as electric motors, industrial fans and continuous process equipment. MR Accesorios Industriales supplies this line throughout Argentina.
The designation of this series combines several suffixes that indicate construction characteristics. TN9 indicates a polyamide cage with fiberglass reinforcement, suitable for high temperatures. C4 indicates an internal clearance greater than normal, intended for assemblies with tight fits or significant thermal gradients. HLHT identifies an execution with high-temperature lubricant and special heat treatment. A specific example is 6204 TN9/C4HLHT23, where the final digits refer to the lubricant variant. To correctly interpret each code, it is key to be guided by the suffixes and not only by the series number.
This type of bearing is used in industries where operating temperatures continuously exceed 100 °C. It is common in large electric motors, induced draft fans, ovens, dryers and process equipment in chemical or food plants. In Argentina, it is found in the cement industry, steel industry and waste treatment plants. Its ability to withstand expansion without losing precision makes it suitable for assemblies where the shaft and housing work at different temperatures.
To select correctly, take into account the internal clearance: a C4 is looser than a CN and prevents the bearing from seizing when the shaft expands. The TN9 cage must not be used in applications with temperatures above those specified for polyamide. The HLHT lubricant is formulated for high temperature and must not be mixed with other greases. During mounting, verify alignment and avoid blows that could damage the cage. If the bearing works near heat sources, consider cooling the housing.
Regarding equivalences, deep groove ball bearings with similar suffixes from other brands can be interchanged if dimensions and internal clearance match. However, not all manufacturers use the same nomenclature for polyamide cages or heat treatments. Therefore, when looking for a replacement, it is essential to compare not only the diameter and width, but also the clearance and the type of cage. MR Accesorios Industriales can advise you on interchangeability according to the exact code.

Frequently Asked Questions
- What are the dimensions of the SKF 6204 TN9/C4HLHT23 bearing?
- The SKF 6204 TN9/C4HLHT23 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 C4 suffix mean on this bearing?
- C4 indicates an internal clearance greater than normal. It is used when the bearing works with tight fits or high temperatures, since it compensates for shaft expansion and prevents the balls from being left without clearance.
- Does the TN9 cage withstand high temperatures?
- The TN9 cage is made of reinforced polyamide, suitable for moderate temperatures. For applications with extreme heat, verify the maximum permitted temperature, since another cage material may be necessary.
- Can I replace this bearing with one from another brand?
- Yes, if dimensions, internal clearance and type of cage match. Not all manufacturers use the same nomenclature, so it is important to compare the technical specifications and not only the series number.
