The DBH 5243 radial shaft seal is a lip seal designed for 20 mm rotating shafts, with a 33 mm housing and 10 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 transmission equipment. MR Accesorios Industriales supplies this official brand and advises you to choose the correct size.

This item is a radial shaft seal from the DBH line, identified by code 5243. Its dimensions are 20 mm shaft, 33 mm housing and 10 mm height. The Lx design corresponds to a single sealing lip with spring, intended for rotating shafts with lubrication. The 5243 designation follows the manufacturer's coding and should not be confused with inch dimensions or other profiles in the same category. It is a precision part that works in direct contact with the shaft and housing.

Typical applications for a 20x33x10 mm seal include centrifugal pumps, low-power electric motors, reducers, mixers, fans and belt or chain transmission equipment. It is also used in machine tools, washing equipment and hydraulic systems where oil or grease needs to be contained. In all cases, the seal protects the bearings and extends the service life of the assembly, provided it is installed on a shaft surface in good condition and with adequate lubrication.

To correctly install this seal, verify that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The 10 mm height allows it to be housed in standard cavities. If the shaft has a groove or greater wear, consider a seal with an auxiliary lip or an alternative size. The selection depends on speed, temperature and the type of fluid to be retained.
