The DBH 6783 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants on rotating shafts. It is mounted in cylindrical housings and works on the shaft with a flexible lip that maintains contact even with slight misalignment. It is a common wear part in gearboxes, pumps, electric motors and transmission equipment, where an early leak compromises the service life of bearings and gears.

This item is identified with the designation 6783 and corresponds to a seal of Ms design. Its dimensions are shaft 28.5 mm, housing 36.5 mm and height 6.00/7.50 mm. That double height indicates that the seal has a longer lip or a reinforced section that adapts to housings with a shoulder or to assemblies where greater rigidity is needed. The Ms design defines the geometry of the lip and the metal body, intended for oil retention in continuous rotation applications.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, spindles and belt or chain transmission equipment. In all these cases the seal separates the lubricant from the environment and protects the bearings from dust, water or particles. It is also used in machine tools and process equipment where lubricant cleanliness is critical for precision and durability.

To install a radial shaft seal, verify that the shaft has no burrs or wear and that the housing is clean and free of deformation. The lip is lubricated before insertion and is pressed in with a tube of suitable diameter so as not to damage it. Shaft eccentricity and housing alignment influence the life of the seal: if they exceed the allowable values, leakage appears prematurely. In selection, in addition to the dimensions, consider the type of fluid, the working temperature and the peripheral speed of the shaft.
