The NTN deep groove ball bearing of the JRLLU series is a single row bearing with contact seals, designed to withstand moderate radial and axial loads in both directions. It is used in equipment requiring low friction and protection against contaminants, such as electric motors, pumps, fans and machine tools. Its sealed construction makes it suitable for dusty or humid environments, reducing maintenance and extending the service life of the assembly.
The JRLLU series designation is interpreted as follows: the initial number (for example, 6808, 6809, 6810, 6811) indicates the size and dimensional series; the letters JR identify an execution with a steel sheet cage and optimized design; LLU corresponds to a double-lip contact seal on both sides. This combination provides protection against particles and lubricant retention. The examples 6808JRLLU, 6809JRLLU, 6810JRLLU and 6811JRLLU show how the code varies according to size. To select, take into account the bore, outer diameter and width your equipment requires.
In Argentine industry, these bearings are found in low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. They are also used in equipment in the food, textile and chemical industries, where the seal prevents the entry of dust and moisture. Their ability to withstand combined loads makes them versatile in belt and gear drives. MR Accesorios Industriales sells this line for replacement and new projects.
To choose correctly, verify the appropriate internal clearance for the application: normal clearance is suitable for most cases, while increased clearance may be necessary if there are thermal interferences. The LLU seal is already factory-lubricated with long-life grease; it does not require relubrication under normal conditions. During mounting, ensure precise alignment between shaft and housing, and avoid striking the seals. If the environment is very aggressive, consider additional protections.
As for equivalents, sealed deep groove ball bearings from other brands can be interchanged if dimensions and seal type match. Suffixes vary: for example, 2RS or DDU indicate contact seals, similar to LLU. Always confirm internal clearance and lubrication. If you have the code from another brand, we can indicate the equivalent NTN reference. Interchangeability is possible, but it is essential to verify operating conditions so as not to compromise performance.

Frequently Asked Questions
- What does the LLU suffix mean on an NTN bearing?
- LLU indicates that the bearing has a double-lip contact seal on both sides. This protects against the entry of contaminants and retains the lubricating grease, ideal for dusty or humid environments.
- Does this bearing need maintenance?
- No, bearings with LLU seals come factory-lubricated with long-life grease. Under normal operating conditions they do not require relubrication, which reduces maintenance tasks.
- Can I replace a bearing from another brand with this NTN one?
- Yes, if the dimensions and seal type match. Suffixes may vary between manufacturers, but interchangeability is possible. Ask us with your bearing code and we'll indicate the equivalent.
