The DBH 9172 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain oil or grease and prevent the entry of dust, water or particles. Its A 073 design combines a sealing lip with a metal body that fits by press fit. It is used in gearboxes, pumps, electric motors and transmission equipment where bearings and lubricant must be protected.

This item is a DBH radial shaft seal with designation 9172. Its dimensions are 50 mm shaft, 67.5 mm housing and 8.00/13.50 mm height, with A 073 design. That double height indicates that the lip protrudes from the housing: the 8 mm portion enters the cavity and the 13.50 mm corresponds to the sealing lip. The A 073 design defines the geometry of the lip and the internal spring that maintains contact on the shaft.

It is used in equipment with rotating shafts where lubricant must be contained and contaminants excluded. It appears in gearboxes, centrifugal pumps, electric motors, compressors, mixers and conveyors. It is also used in applications exposed to dust or water, such as industrial washing machines or process equipment. It is a wear part: over time the lip hardens or becomes marked and starts to leak.

To install it, verify that the shaft is clean, free of burrs or marks, and that the sealing surface has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking the lip. If the housing has a shoulder, respect the depth. When selecting a replacement, compare shaft diameter, housing diameter and height; the A 073 design must match or be compatible with the cavity.
