This SKF ZTN series deep groove ball bearing features an LLHT seal and handles radial and axial loads in both directions. The sealed design keeps lubricant in and contaminants out, which helps extend service life. It is commonly found in electric motors, pumps, fans, and transmissions. At MR Industrial Accessories, we supply this brand and can help you match the right bearing to your application.
The part number tells you a lot about the bearing. Take 6004-2ZTN9/C3LLHT23: the first digits give the size and series. The 2ZTN9 suffix means two protective shields (Z), a special treatment (TN9), and a groove for a retaining ring (N9). The /C3LLHT23 portion indicates radial internal clearance greater than normal (C3) and a high-temperature lubricant (LLHT23). Reading these codes correctly helps you pick the right bearing for your equipment.
You will find this bearing in food, chemical, petrochemical, and process industry equipment that runs in moisture, dust, or high temperatures. It appears in electric motors for centrifugal pumps, industrial fans, conveyor belts, and machine tools. The LLHT seal and C3 clearance suit applications where temperature swings and thermal expansion demand extra tolerance.
When selecting, consider load type, speed, and environmental conditions. The LLHT seal retains lubricant well and blocks contaminants, but confirm the lubricant is compatible with your operating temperature. Choose C3 clearance when the inner and outer rings see thermal differences, or when mounting requires more tolerance. During installation, ensure precise alignment and avoid impacts that could damage seals or raceways.
For equivalences, SKF bearings in this series can interchange with other brands that use the same standardized designations, such as FAG, NSK, or NTN, provided dimensions and suffixes match. Always check technical specifications, as materials or treatments may differ. If you need help, contact us and we will assist you in finding the right replacement.

Frequently asked questions
- SKF 6004-2ZTN9/C3LLHT23 bearing: what are its dimensions?
- SKF 6004-2ZTN9/C3LLHT23 measures 20 mm across the bore and 42 mm across the outside diameter; its width is 12 mm (20 x 42 x 12 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6004.
- What does the LLHT suffix mean on this bearing?
- LLHT indicates the seal type and the high-temperature lubricant built into the bearing. This seal retains lubricant and protects against contaminants, which extends service life in demanding environments.
- When should I choose a bearing with C3 clearance?
- C3 clearance is advisable when there are significant thermal gradients between the inner and outer rings, as it compensates for expansion. It is also used when mounting requires greater tolerance or when the bearing operates at high speeds.
- Can I replace this bearing with one from another brand?
- Yes, if dimensions and suffixes match. Brands like FAG, NSK, or NTN make equivalent bearings under the same standards. We recommend verifying technical specifications and, if in doubt, consulting us with the original part number.
