The JRLLU line from NTN covers single row deep groove ball bearings that carry moderate radial and axial loads in either direction. Both sides are fitted with contact seals, so the bearing keeps its grease in and keeps dust and moisture out. This makes the series a practical choice for electric motors, pumps, fans and machine tools, and for plants where washdown, humidity or airborne particles are part of daily operation.

Reading the code helps you order the right size. The leading digits, such as 6808, 6809, 6810 or 6811, set the dimensional series. The letters JR signal a pressed steel cage and an optimized internal design. The LLU suffix means a double-lip contact seal on each side. Put together, references like 6808JRLLU, 6809JRLLU, 6810JRLLU and 6811JRLLU differ mainly by size, so match bore, outer diameter and width to your equipment before ordering.

Typical applications include low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. The sealed design also suits food, textile and chemical plants, where dust and moisture are present. Because the bearing handles combined radial and axial loads, it works well in belt and gear drives as well.

For selection, check the internal clearance your application needs. Normal clearance covers most cases; increased clearance may be required where thermal interference is expected. The LLU seal retains factory-filled long-life grease, and under normal conditions no relubrication is needed. During mounting, align shaft and housing carefully and do not strike the seals. In very aggressive environments, add extra protection.

Interchange is possible with sealed deep groove ball bearings from other makers when dimensions and seal type match. Suffix conventions differ: 2RS or DDU, for instance, also denote contact seals similar to LLU. Confirm clearance and lubrication before substituting. If you only have another brand's code, our team can point you to the equivalent NTN reference.
