Its dimensions of 64 mm shaft diameter, 80 mm housing and 8 mm height make it suitable for gearboxes, pumps and medium-sized electric motors. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your application.

This item is a DBH radial shaft seal, identified by the code 5191. Its dimensions are 64 mm shaft diameter (d), 80 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a single sealing lip with spring, intended for rotating shafts with continuous lubrication. The 5191 designation groups these standard dimensions, so any equivalence inquiry must start from those three values.

It is used in equipment where oil or grease leaks and the entry of dust or water must be prevented: gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. It also appears in agricultural and industrial applications where the shaft rotates continuously and the service temperature is moderate. It is a wear part that should be checked at every preventive maintenance interval.

To install it, make sure the shaft has the proper hardness and surface finish, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and use an installation sleeve so as not to damage the spring. When selecting, take into account the peripheral speed, temperature and type of fluid. If the seal works under high pressure, consider a design with additional reinforcement.
