The DBH 5052 radial shaft seal is a lip seal designed for rotating shafts with a 22 mm shaft diameter, 40 mm housing bore and 7 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in pumps, electric motors, gearboxes and power transmission equipment operating in factories, plants and industrial facilities.

This DBH 5052 oil seal has a shaft diameter of 22 mm, a housing bore of 40 mm and a height of 7.00 mm. The Lz design corresponds to a configuration with a sealing lip and spring that maintains contact on the shaft. The 5052 designation identifies the exact size within the DBH line. It is a radial-type seal, designed to be press-fitted into the housing and seal against the surface of the moving shaft.

It is used in equipment with continuous rotation and the need to contain oil or grease: centrifugal pumps, electric motors, gearboxes, mixers, conveyors and agricultural or road machinery. It also appears in applications where the environment has dust or moisture and bearings need protection. In all cases, the seal works as a dynamic barrier and its correct selection prevents leaks and contamination.

To install it, check that the shaft has no burrs or wear and that the 22 mm dimension matches the tolerance specified by the equipment manufacturer. Lubricate the lip before inserting it and seat the seal perpendicular to the shaft. When choosing a replacement, take into account the shaft diameter, housing bore and height; also the type of elastomer and the spring, depending on the temperature and the fluid to be retained.
