The DBH 9955 radial shaft seal is a lip seal that mounts on a 16 mm shaft and closes against a 30 mm housing, with a total height of 11.30 mm. Its A 355 design combines a sealing lip with a metal body that press-fits into the cavity. It is used to retain lubricant and block the entry of dust, water or particles in gearboxes, pumps, electric motors and power transmission equipment.

This item is a radial shaft seal from the DBH line, identified with part number 9955. Its nominal dimensions are 16 mm shaft, 30 mm housing and 11.30 mm height, and it corresponds to design A 355. That combination defines a compact-section seal, intended for small-diameter shafts where axial space is limited. The elastomeric lip runs on the shaft surface and the outer body holds the part firmly inside the housing.

Typical applications for a seal of these dimensions appear in equipment with thin transmission shafts: small electric motors, centrifugal pumps, speed reducers, compressors, machine tools and process equipment. It is also found in gearboxes and mechanisms where oil or grease must be separated from the outside environment. In all cases it serves two functions: it prevents lubricant leaks and slows the advance of contaminants toward the bearings or bushings.

To install it properly, check that the shaft has no burrs or deep marks in the contact area, and that the housing is clean and free of deformation. Lubricate the lip before inserting it and do so with a tool that bears evenly on the metal body, never on the elastomer. When selecting a replacement, take into account the shaft diameter, housing diameter, height and design type, because a variation in any of those values changes the fit and the sealing.

To quote part number 9955, send us the shaft, housing and height dimensions shown on your equipment. With that data we can look for an alternative within the same radial shaft seal category or confirm whether design A 355 is the one that corresponds to your application. It also helps if you tell us the type of lubricant and the operating conditions to better guide the selection.
