The SKF ZTN series deep groove ball bearing with LLHT seal is a component designed to support radial and axial loads in both directions. Its sealed construction makes it suitable for environments with contaminants, retaining the lubricant and extending its service life. It is used in a wide variety of industrial equipment, such as electric motors, pumps, fans and transmissions. At MR Accesorios Industriales we sell this brand and advise you so that you choose the correct bearing for your application.
The designation of these bearings combines several suffixes that indicate specific characteristics. For example, in 6004-2ZTN9/C3LLHT23, the numeric prefix identifies the size and series. The suffix 2ZTN9 indicates that the bearing has two protective shields (Z) with special treatment (TN9) and a groove for a retaining ring (N9). The part /C3LLHT23 indicates a radial internal clearance greater than normal (C3) and a high temperature lubricant (LLHT23). Knowing these codes allows you to select the right bearing for your equipment.
This type of bearing is used in industries such as food, chemical, petrochemical and process industries, where equipment operates in environments with moisture, dust or high temperatures. In Argentina, it is common to find it in electric motors of centrifugal pumps, industrial fans, conveyor belts and machine tools. Its LLHT seal and its C3 clearance make it ideal for applications where greater tolerance to temperature and dimensional variations due to thermal expansion is required.
To select correctly, take into account the type of load, the rotation speed and the environmental conditions. The LLHT seal offers good lubricant retention and protection against contaminants, but verify that the lubricant is compatible with the working temperature. The C3 clearance is recommended when there are thermal differences between the inner and outer rings, or when greater tolerance in mounting is required. During mounting, ensure precise alignment and avoid blows that could damage the seals or raceways.
Regarding equivalences, SKF bearings of this series can be interchanged with those of other brands that follow the same standardized designations, such as FAG, NSK or NTN, as long as the dimensions and suffixes match. However, always verify the technical specifications, since there may be differences in materials or treatments. If you need assistance, contact us and we will help you find the right replacement.

Frequently Asked Questions
- What are the dimensions of the SKF 6004-2ZTN9/C3LLHT23 bearing?
- The SKF 6004-2ZTN9/C3LLHT23 bearing has a 20 mm bore, a 42 mm outside diameter and a 12 mm width (20 x 42 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6004.
- What does the LLHT suffix mean on this bearing?
- LLHT indicates the type of seal and the high temperature lubricant incorporated in the bearing. This seal offers good lubricant retention and protection against contaminants, which extends service life in demanding environments.
- When is it advisable to choose a bearing with C3 clearance?
- C3 clearance is recommended when there are significant thermal gradients between the inner and outer rings, as it compensates for expansion. It is also used in applications where greater tolerance in mounting is required or when the bearing operates at high speeds.
- Can I replace this bearing with one from another brand?
- Yes, as long as the dimensions and suffixes match. Brands such as FAG, NSK or NTN manufacture equivalent bearings under the same standards. We recommend verifying the technical specifications and, if you have doubts, consulting us with the original part number.
