The DBH 9573 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its Mx design and dimensions of 11.12 mm shaft, 22.22 mm housing and 9.52 mm height place it in small-shaft equipment where axial space is limited. It is used in pumps, small electric motors, reducers and portable tools.

This item is a DBH 9573 radial shaft seal, identified by the code 9573, with an Mx design. Its dimensions are 11.12 mm shaft diameter (d), 22.22 mm housing diameter (D) and 9.52 mm height (h). That combination of a small shaft with a 22.22 mm housing and a height close to 9.5 mm responds to standardized cavities in compact equipment. The sealing lip works on the shaft and the outer diameter fits into the housing to prevent leaks.

Typical applications for a seal of this size appear in small centrifugal pumps, low-power electric motors, hollow-shaft reducers, compact gearboxes, small compressors and portable tools. It is also found in transmission equipment where oil or grease must be separated from the environment. In all cases, the seal protects the bearings and prevents lubricant loss, which is the most common cause of premature failure.

To install it, verify that the shaft has no burrs or wear on the sealing track and that the housing is clean and free of dents. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a tube or driver that presses on the outer diameter, never on the lip. If the shaft shows a marked groove, consider a nearby size or a seal with the lip in a different position so the failure is not repeated.

If you need an equivalent or a nearby size, send us the code 9573 or the shaft, housing and height dimensions along with a photo of the old seal. The code engraved on the seal or the model of the equipment where it is mounted also helps. With that data we review alternatives within the radial shaft seal category and confirm which option fits without modifying the housing.
