The DBH 6743 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that could damage bearings and gears. With dimensions of 25 mm shaft, 45 mm housing and 10 mm height, and an Lx design, it is press-fitted into crankcases, pumps, electric motors and gearboxes. MR Accesorios Industriales sells it as part of its line of seals and oil seals for industrial maintenance.

This item is a radial shaft seal from the DBH brand, identified with code 6743. Its dimensions are 25.00 mm shaft diameter (d), 45.00 mm housing diameter (D) and 10.00 mm height (h). The Lx design corresponds to a seal with a single sealing lip and spring, without an external dust lip, suitable for applications where axial space is limited. The lip elastomer and the metal case ensure sealing under continuous rotation conditions.

Typical applications for this seal include centrifugal pumps, electric motors, speed reducers, gearboxes and transmission shafts. In all cases, the DBH 6743 seal seals the passage of oil or grease between the shaft and the housing, protecting the bearings and preventing leaks. It is a wear part that should be replaced at every preventive maintenance interval or when lubricant leaks are detected.

For correct installation, check that the shaft has adequate surface hardness and a fine surface finish, and that the housing is clean and free of burrs. Lubricate the lip with the same service oil or grease before inserting it, and install the seal with an installation tool that presses on the metal case, never on the lip. Selection must consider peripheral speed, temperature and the type of fluid to be retained.
