The DBH 5274 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent contaminants from entering equipment with a rotating shaft. Its dimensions of 50.8 mm shaft diameter, 80 mm housing and 6.35 mm height make it suitable for assemblies requiring a compact and efficient closure. It is a common replacement part in pumps, electric motors, gearboxes and transmission systems operating with medium-section shafts.

This item is a DBH brand radial shaft seal, identified by the code 5274. Its dimensions are 50.8 mm shaft diameter (d), 80 mm housing diameter (D) and 6.35 mm height (h). The Ls design corresponds to a single lip configuration with a spring, intended for rotating shafts with lubrication. The manufacturer's nomenclature makes it quick to locate in the catalog and verify its interchangeability with other brands.

Seals of this size are used in equipment where the shaft rotates inside a fixed housing and oil or grease needs to be contained. They appear in centrifugal pumps, electric motors, reducers, mixers and machine tools. They are also used in applications with moderate exposure to dust or water, provided the lip material is compatible with the fluid and the working temperature.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the height. It is essential that the shaft shows no wear or scoring in the contact area, and that the housing is clean and free of burrs. The Ls design requires a shaft surface with adequate hardness and roughness to prevent premature leaks. Installation with unsuitable tools can damage the lip and nullify the seal.
