The DBH 5127Sil radial shaft seal is a lip seal that mounts on a 42 mm shaft and fits into a 72 mm bore, with a height of 10 mm. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles, working against the moving shaft. It is a common wear part in gearboxes, pumps and motors, and is replaced when oil leakage or dirt ingress appears.

This DBH 5127Sil oil seal has a shaft diameter of 42 mm, a housing diameter of 72 mm and a height of 10 mm. The Lz design corresponds to a seal with a sealing lip and a spring that maintains contact pressure on the shaft. The 5127Sil nomenclature identifies the size and construction type within the DBH line. It is manufactured with an elastomer resistant to mineral oils and greases, and a metal case that gives it rigidity for press fitting.

It is used in equipment where a rotating shaft exits a housing: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools. It also appears in agricultural and industrial applications where lubricant must be contained and bearings protected from the environment. Whenever there is a 42 mm shaft and a 72 mm housing, this seal is a direct candidate for replacement.

To install it, verify that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and seat the seal with a tube or press that bears on the case, never on the lip. If the shaft shows a deep groove, consider a neighboring size or a seal with an offset lip. Selection depends on speed, temperature and the type of fluid.
