The DBH 8481 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 63 mm shaft diameter, 80 mm housing and 12 mm height, and Mx design, it is press-fitted into crankcases, covers and gearboxes. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your equipment.

The DBH 8481 is a radial shaft seal with Mx design, with the following dimensions: shaft diameter 63 mm, housing diameter 80 mm and height 12.0 mm. The Mx design corresponds to a single-lip seal with a spring, designed for rotating shafts where the goal is to retain lubricant and exclude dust. The 8481 nomenclature identifies this size within the DBH line, and the assembly is press-fitted into the housing with the lip resting on the shaft.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, transmission shafts and continuous process equipment. In all cases it performs the function of preventing oil leaks to the outside and stopping contaminants from entering the bearing or gear. It is a wear part that should be replaced when dripping appears, the lip hardens or shaft play is detected.

To select and install the seal, keep in mind that the shaft diameter must be within the recommended tolerance, with a surface roughness suitable for not damaging the lip. The housing must be clean, free of burrs and with the entry chamfer in good condition. Lubricate the lip before installing, check that the spring is on the side of the fluid to be retained and avoid striking the casing during installation.
