The DBH 9934 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the assembly and prevent the ingress of contaminants such as dust, water or particles. With dimensions of 40 mm shaft diameter, 74 mm housing and a height of 10.00/18.50 mm, it is used in gearboxes, pumps, electric motors and industrial equipment in general. MR Accesorios Industriales supplies this official brand and advises you so you choose the correct seal for your application.

This item is a DBH brand radial shaft seal, identified with the code 9934. Its main dimensions are: shaft diameter (d) 40 mm, housing diameter (D) 74 mm and height (h) 10.00/18.50 mm. The A 103 design corresponds to a seal with a sealing lip and metal body, suitable for rotating shafts. The double height (10.00/18.50 mm) indicates that the seal has an auxiliary lip or dust lip that protrudes from the housing, offering additional protection against external contamination.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the DBH 9934 seal seals the shaft passage through the housing, preventing oil or grease leaks and protecting bearings and gears from the ingress of dirt. It is a critical part for the service life of the machine and for keeping the environment clean.

To correctly install this seal, verify that the shaft measures 40 mm and the housing 74 mm, with suitable tolerances and no burrs. Lubricate the lip with compatible grease before installation and make sure the seal enters perpendicular to the shaft. The height of 10.00/18.50 mm must match the housing depth and the available space. If the shaft shows wear, consider using a seal with the lip in a different position or a wear sleeve.
