The DBH 8354 radial shaft seal is a lip seal that stops lubricant from escaping and blocks the entry of dust, water or particles in equipment with a rotating shaft. Because of its dimensions —39 mm shaft, 50.40 mm housing and 8.50 mm height— it is installed in gearboxes, pumps, electric motors and transmissions where axial space is limited. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a radial shaft seal from the DBH brand, identified by part number 8354. Its attributes are: shaft diameter 39 mm, housing diameter 50.40 mm and height 8.50 mm. The A 235 design defines the geometry of the lip and the metal body, intended to retain oil or grease on a shaft rotating inside a cavity. It is a common replacement part in industrial maintenance, not a custom component: it is selected by those three dimensions and by the type of service.

Typical applications for a seal of these dimensions appear in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. It is also used in machine tools, industrial washing machines and irrigation systems where the lubricant must be separated from the environment. In all cases it performs the same function: preventing leaks and protecting the bearings or bushings behind the seal, extending the service life of the assembly.

To install it properly, verify that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. The lip is lubricated before inserting the seal, and the part is seated straight with a suitable tube or shim, never by striking the lip directly. If the shaft shows a deep groove, it is advisable to consider a seal with an offset lip or to repair the surface. Selection depends on the fluid, temperature and rotation speed.

If you need an equivalent or a nearby size, send us part number 8354 together with the shaft, housing and height dimensions. A photo of the old part or the assembly drawing also works. With that data we review alternatives within the DBH line and other brands we carry, and we confirm which option fits without modifying the housing. You do not need to have the exact designation: the dimensions are enough to search.

MR Accesorios Industriales has more than 80 years in the industry and carries the DBH brand as part of its line of seals. Whether this seal is for a one-off repair or to keep the plant supplied, write to us on WhatsApp with the part number and we will send you the quote. We can also advise you on installation or suggest the equivalent seal if the 8354 is not available at the time.
