The DBH 8391 radial shaft seal is a lip seal designed to keep lubricant in and prevent contaminants from entering rotating shafts. With dimensions of 19 mm shaft diameter, 27 mm housing bore and 5 mm height, and an Lt design, it is used in equipment where axial space is limited and an effective barrier against dust, water and particles is required. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a DBH 8391 radial shaft seal, identified by its designation 8391. Its main attributes are: shaft diameter (d) of 19 mm, housing bore diameter (D) of 27 mm and height (h) of 5.00 mm. The Lt design corresponds to a lip configuration suited to rotating shafts at moderate speeds. The seal combines an elastomeric element with a metal reinforcement that gives it rigidity and ensures a firm fit in the housing. Its function is to retain lubricant inside the assembly and block the entry of dirt, extending the life of bearings and bushings.

Typical applications for a seal of these dimensions include small gearboxes, pumps, electric motors, reducers and power transmission equipment. It is also found in agricultural machinery, conveyors and hydraulic systems where reliable sealing is needed in compact spaces. As a wear component, it should be replaced when leaks appear or when the lip shows hardening or cuts. It is compatible with shafts that have suitable hardness and roughness for dynamic sealing.

To install this seal, check that the housing and shaft are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and press evenly on the outer ring, never on the lip. Selection must consider rotation speed, working temperature and the type of fluid to be retained. If the shaft shows wear, consider a nearby size or a design with an auxiliary lip. The designation 8391 and the dimensions 19 x 27 x 5 mm are the key data for ordering the replacement.
