The DBH 6672 radial shaft seal is a lip seal mounted in a machine housing to retain lubricant and prevent the ingress of dust, water or particles. With 25 mm shaft diameter, 40 mm housing diameter and 7 mm height, and A 115 design, it is a commonly used size in industrial equipment. MR Accesorios Industriales carries this brand and advises you on choosing the correct seal for your application.

This item is a DBH radial shaft seal, identified by code 6672, which corresponds to a seal of 25.00 mm shaft diameter, 40.00 mm housing diameter and 7.00 mm height. The A 115 design defines the geometry of the lip and the metal body, intended for rotating shafts with lubrication. It is a common replacement part in gearboxes, pumps, electric motors and power transmission equipment. Its function is twofold: to keep oil or grease inside the assembly and to block the entry of external contaminants.

Typical applications for a seal of this size include speed reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. It is also used in agricultural, textile and food machinery, where protection against dust and water is critical. In all cases, the seal runs on a rotating shaft and inside a machined housing, and its service life depends on concentricity, shaft roughness and correct lubrication of the lip.

To select and install this seal, take into account the rotation speed, working temperature and the type of fluid to be retained. Verify that the shaft has no burrs or wear in the contact area and that the housing is clean and free of deformation. The lip must be lubricated before installation and the part is inserted with a suitable tool, without striking the seal. If the shaft is damaged, consider a wear sleeve or an alternative size.

If you need an equivalent or a nearby size, the most practical approach is to send us the code 6672 or the current dimensions (shaft diameter, housing diameter and height) along with a photo or sample of the old seal. With that data we can look for an alternative within the same brand or another brand we carry, respecting the design and material. We can also advise you if the original seal has any particular feature, such as a double lip or an additional spring.
