The DBH 1251Vit radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and water from entering rotating shafts. With dimensions of 39 mm shaft diameter, 50 mm housing diameter and 7 mm height, and Lx-R H design, it is press-fitted into crankcases, covers and gearboxes. It is a wear part that should be replaced when lubricant leakage or lip play appears. MR Accesorios Industriales sells it.

This item is a DBH 1251Vit radial shaft seal, identified by its designation 1251Vit. Its dimensions are 39 mm shaft diameter (d), 50 mm housing diameter (D) and 7.00 mm height (h). The Lx-R H design indicates a configuration with a sealing lip and reinforced body, suitable for retaining lubricant in one direction and withstanding continuous shaft friction. DBH is a brand MR sells, so the replacement part keeps the geometry and material intended for this application.

Typical applications for a seal of these dimensions are found in gearboxes, pumps, electric motors, transmission shafts and process equipment. It is also used in agricultural machinery, transport and industrial plants where rotating shafts must be isolated from the environment. As a wear part, its service life depends on speed, temperature and lubricant cleanliness. If the seal leaks, oil migrates to unwanted areas and can carry contaminants into the mechanism.

To install a radial shaft seal, check that the shaft has no burrs or deep marks and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal perpendicular to the shaft with an installation tube that presses on the outer edge, never on the lip. If the shaft shows wear, consider a repair sleeve. Selection must take peripheral speed and lubricant type into account; if in doubt, consult us with the equipment data.
