The DBH 8779 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. Its dimensions of 19 mm shaft, 30 mm housing and 5.50 mm height place it in small-sized equipment, where axial space is limited. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

This item is a DBH 8779 radial shaft seal with the following dimensions: shaft diameter 19 mm, housing diameter 30 mm and height 5.50 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The designation 8779 identifies the size within the DBH line and is the data you should provide along with the three dimensions to avoid confusion with seals of similar cross-section.

It is used in small gearboxes, electric motors, centrifugal pumps, compressors, fans and power transmission equipment where the shaft passage through a cover or casing must be sealed. It also appears in machine tools, washing equipment and agricultural or road applications where the environment has dust or moisture. In all these cases the seal protects the bearing and the lubricant, and extends the service life of the assembly.

To install it, verify that the shaft is clean, free of burrs or wear marks in the contact area, and that the housing has no dents. Lubricate the lip with the same grease or oil as the equipment before inserting it, and place the seal perpendicular to the shaft, without tilting it. If the shaft shows a groove or noticeable wear, consider a seal with the lip in another position. The selection depends on the type of lubricant, the speed and the working temperature.

If you need an equivalent, send us the code 8779 along with the shaft, housing and height dimensions, and a photo of the old seal if you have it on hand. With that data we can look for an alternative within the DBH line or another brand we carry, always respecting the housing and shaft tolerances. We can also advise you if the Lx design is not the right one for your application.
