The DBH 9339 radial shaft seal is a lip seal that mounts in a component's housing and seals against a rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. With a 30 mm shaft, 72 mm housing and 8 mm height, it is a common size in industrial equipment. MR Accesorios Industriales carries this brand and helps you confirm it is the right part for your equipment.

This item is a DBH radial shaft seal with designation 9339. Its dimensions are 30 mm shaft diameter, 72 mm housing diameter and 8 mm height. The Lx design corresponds to a seal with a sealing lip and a construction configuration that defines how it seats in the housing. It is a compact-section part, intended for transmission shafts, gearboxes, pumps and motors where oil must be separated from the environment.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. In every case it performs the same function: preventing lubricant leaks and protecting the bearings from contaminant ingress. When the seal runs on a worn or loose shaft, the leak returns even if the part is new, so it is advisable to check the shaft condition before replacing.

To mount it, verify that the shaft and housing diameters match the 30 mm and 72 mm on the product page, and that the 8 mm height fits without forcing. The lip is lubricated before assembly and seated with a tube of the appropriate diameter, without striking the edge. If the shaft has burrs or a groove, the lip is damaged during mounting. Cleaning the housing and using the right tool are as important as the quality of the seal.

If you need an equivalent or a nearby size, send us the part number 9339 along with the shaft, housing and height dimensions. A photo of the old part or the assembly drawing also helps. With that data we review alternatives within the same radial shaft seal category and confirm which option fits without modifying the housing.
