The DBH 9440 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating shafts. With dimensions of 37 mm shaft diameter, 55 mm housing diameter and 10 mm height, it is press-fitted into gearboxes, covers and housings. It is a key component in gear reducers, pumps and electric motors, where reliable sealing extends the service life of bearings and gears.

This DBH 9440 oil seal has an Lx design and is identified by its dimensions: 37 mm shaft diameter (d), 55 mm housing diameter (D) and 10 mm height (h). The sealing lip, made of elastomer, runs on the rotating shaft, while the outer body ensures a firm fit in the housing. It is a standard component within the radial shaft seal category, intended for applications requiring oil or grease retention and protection against dust and dirt.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the DBH 9440 oil seal retains lubricant inside the assembly and prevents external agents from entering the bearings or gears. It is commonly found in industrial machinery, process equipment and vehicles, where efficient sealing reduces wear and maintenance downtime.

To select this oil seal correctly, verify that the shaft and housing dimensions match those of the equipment. Installation must be carried out with suitable tools to avoid damaging the lip; lubricating the lip before inserting it is recommended, and make sure the shaft has no burrs or excessive wear. Rotation speed, operating temperature and the type of fluid to be retained are factors to consider when choosing the lip material and spring. If you have any doubts, ask us.
