The DBH 5231Sil radial shaft seal is a single lip seal with a spring, designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of contaminants, such as dust or water, that accelerate wear on bearings and bushings. With dimensions of 45 mm shaft diameter, 65 mm housing and 8 mm height, and an Lx design, it is a common replacement part in industrial equipment. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal.

This item is a radial shaft seal from the DBH brand, identified with the code 5231Sil. Its standard dimensions are: shaft diameter (d) of 45 mm, housing diameter (D) of 65 mm and height (h) of 8.00 mm. The Lx design corresponds to a seal with a single sealing lip and spring, without an outer dust lip, suitable for applications where axial space is limited and an effective barrier against oil or grease leaks is required. The 5231Sil designation makes it easy to locate in catalogs and spare parts management systems.

Typical applications for this seal include gearbox housings, centrifugal pumps, electric motors, drive shafts and continuous process equipment. In all cases, its function is to protect bearings and gears from the entry of particles and to keep lubrication at the exact point. Because of its 45x65x8 mm size, it is common in medium-sized equipment, where reliable sealing is needed at moderate speeds and with the presence of oil or grease.

To install this seal correctly, verify 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 oil or grease used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows wear, consider a seal with an offset lip. Selection must take into account peripheral speed, temperature and the type of fluid to be retained.
