The DBH 5818Sil radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 12 mm shaft diameter, 22 mm housing diameter and 7 mm height, and Lz design, it is a common replacement part in equipment with small-diameter shafts. MR Accesorios Industriales supplies this official brand and advises you on choosing the right size.

This item is a DBH radial shaft seal with the designation 5818Sil, with the following dimensions: shaft diameter (d) 12 mm, housing diameter (D) 22 mm and height (h) 7.00 mm. The Lz design corresponds to a configuration with a sealing lip and spring, intended for rotating shafts. The lip elastomer runs on the shaft surface, while the outer diameter maintains the fit in the housing. It is a precision part that requires careful handling to avoid damaging the lip during installation.

Typical applications of a 12 x 22 x 7 mm oil seal include small electric motors, gearboxes, water and oil pumps, compressors, fans and low-power transmission equipment. It is also used in agricultural machinery, power tools and process equipment where lubricant must be contained and bearing contamination prevented. In all cases, the selection of the lip material and spring must match the temperature, peripheral speed and type of fluid.

For correct installation, check that the shaft has no burrs or wear and that the housing is clean and free of marks. Lubricate the lip before inserting it and use an installation tube that presses on the outer diameter, never on the lip. The 7.00 mm height should sit flush or slightly recessed depending on the housing design. If the shaft shows a worn surface, consider a repair sleeve or a nearby size to restore the fit.
