The DBH 9973Pol radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of equipment with a rotating shaft. It mounts on 38 mm shafts and 49.20 mm housings, with a height of 7.80/11.80 mm that combines the sealing lip and a protective outer lip. It is a common replacement part in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales carries this brand and advises you on choosing the right seal.

This item is a radial shaft seal from the DBH line, identified by the designation 9973Pol. Its dimensions are shaft (d) 38 mm, housing (D) 49.20 mm and height (h) 7.80/11.80 mm. The A 118-R AH design corresponds to a seal with a sealing lip and an outer protective lip, intended to retain lubricant and exclude dust or water depending on the mounting orientation. The double height indicates that the main lip and the auxiliary lip sit on different planes inside the housing.

Typical applications for this seal include centrifugal pumps, electric motors, gearboxes, rollers and transmission equipment. In every case, the seal works against a rotating shaft and a fixed housing, and its job is to keep lubricant inside the assembly and prevent particles, chips or moisture from entering. It is a wear part that should be replaced when a visible leak appears or when the equipment is taken apart for another reason.

To select and install it correctly, check that the shaft and housing diameters match the dimensions given. The lip must be lubricated before mounting, and the shaft must not have burrs or deep marks in the contact area. If the shaft is worn, consider a repair sleeve or a seal with an offset lip. The 7.80/11.80 mm height must fit into the housing without forcing, with the outer lip facing the side to be protected.
