The DBH 8744 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 75 mm shaft, 108 mm housing and a height of 10/20 mm, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a key part in gearboxes, pumps and industrial equipment where sealing prevents leaks and premature wear. MR Accesorios Industriales sells this official brand and advises you on choosing the right seal.

This item is a radial shaft seal from the DBH brand, identified by part number 8744. Its main dimensions are: shaft diameter 75 mm, housing diameter 108 mm and overall height 10.00/20.00 mm. The A 172 design corresponds to a configuration with a sealing lip and metal body, suitable for press fitting. The double height indicates that the seal has a stepped profile or a section that varies between 10 and 20 mm, which is common in applications with limited axial space. Manufactured with elastomers resistant to oils and greases, it provides an effective barrier against lubricant leakage and dust ingress.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, transmission shafts and continuous process equipment. In the food, chemical or metallurgical industry, where cleanliness and reliability are critical, a properly selected seal extends the life of bearings and gears. It is also used in electric motors and compressors. Its radial design tolerates small misalignments and vibrations, provided it is correctly installed on a ground shaft and a housing with the proper diameter.

To install this seal, verify that the shaft has the recommended hardness and roughness, free of burrs or marks that could damage the lip. Lubricate the lip with the same oil used in the equipment before inserting it, and use an installation tool that presses on the outer diameter, never on the lip. The 10/20 mm height requires respecting the available space in the housing. When selecting, consider peripheral speed, temperature and fluid type. If the original seal has a different designation, we can look for an equivalent with the same dimensions or a nearby size.
