The DBH 5508 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With its dimensions of 28 mm shaft, 47 mm housing and 8 mm height, it is a commonly used part in gearboxes, pumps and medium-sized electric motors. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal for your equipment.

This item is a radial shaft seal from the DBH brand, identified with the code 5508. Its dimensions are 28.00 mm shaft diameter (d), 47.00 mm housing diameter (D) and 8.00 mm height (h). The indicated design is Mz, a construction configuration that defines the shape of the lip and the metal body. It is a rotary sealing component: the flexible lip rests on the rotating shaft and the outer diameter fits into the housing to prevent oil or grease loss.

Typical applications of a seal of these dimensions appear in equipment with transmission shafts: gearboxes, centrifugal pumps, electric motors, reducers and machine tools. It is also used in rollers, mixers and conveyors where a bearing must be protected from dust and moisture. In all cases it works together with a bearing or bushing, and its function is to extend the service life of the lubricant and the raceways, preventing external contamination.

To install it properly, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before inserting it and use a tube or press that rests on the outer diameter, never on the lip. The 8 mm height defines the required axial space. If the shaft has a groove or wear, consider a neighboring size or a design with an auxiliary lip. The selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a close size, send us the complete code, the shaft and housing dimensions, and a photo of the old part. With that data we search the DBH line or another compatible alternative. We can also check whether there is a seal with an Mz design in different heights or diameters. The more precise the information, the faster we give you a useful answer.
