The DBH 9728Pol radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 50 mm shaft, 72 mm housing and 10 mm height, and Lz-R-AH design, it is a common replacement part in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales carries it within its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified with the code 9728Pol. Its dimensions are 50 mm shaft diameter, 72 mm housing diameter and 10 mm height. The Lz-R-AH design defines the geometry of the lip and the body: a profile with a sealing lip and reinforcement that runs on the rotating shaft. It is a compact-section part, designed for housings where axial space is limited and a reliable seal is needed.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases it serves the same function: keeping oil or grease inside the assembly and preventing contaminants from entering from outside. It is also used as a barrier in environments with dust or moderate humidity, where the lip must rest evenly on the shaft.

For proper installation, check that the shaft has no burrs, scratches or wear in the contact area; a damaged shaft ruins the lip within a few hours. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it unevenly. If the housing has a shoulder or a radius, make sure the seal seats fully. Selection depends on the type of lubricant, the speed and the working temperature.

If you need a nearby size or an equivalent, the most practical approach is to send us the code 9728Pol along with the shaft, housing and height dimensions, and a photo or sketch of the housing. With that data we review alternatives within the same radial shaft seal category and confirm which option fits without modifying the machining. We can also verify the Lz-R-AH design against the manufacturer's data sheet if you have doubts about the profile.
