When a shaft exit starts weeping oil, the fix usually comes down to one part: the radial shaft seal. The DBH 5047 is a lip seal that keeps lubricant where it belongs and keeps dust, water and particles out of the bearing cavity. It fits a 47.63 mm shaft in a 75.33 mm housing with a 6.35 mm height, and it uses the Lt design. Maintenance crews run into it on rotating equipment of all kinds, which makes it a sensible item to keep on the shelf.

Reading the code is straightforward. The DBH brand identifies the seal line, and 5047 is the reference for this particular size. The three figures that matter are 47.63 mm for the shaft, 75.33 mm for the housing bore and 6.35 mm for the height. Get those right and the seal will seat correctly; get them wrong and no amount of careful installation will help.

The Lt designation tells you what you are buying: a single lip with a spring. The elastomer lip and the metal case are bonded into one rigid unit that presses into the housing and rides against the rotating shaft. This is a general-purpose sealing configuration. If your equipment calls for a double lip or has to hold back high pressure, this seal is not the right choice and a different variant should be selected.

You will find this size on gear reducers, centrifugal pumps, electric motors, line shafts and process equipment that runs continuously. It also shows up at shaft exits on machine tools, conveyors and splash-lubricated assemblies. The working conditions to check before ordering are shaft speed, operating temperature and the fluid being sealed, since those determine whether the standard elastomer is up to the job.

Installation is where most premature failures happen. The shaft should be clean, with no burrs or score marks, and the sealing surface needs the right roughness. The bore must be machined to the correct tolerance for a press fit. Coat the lip with the same oil or grease the equipment uses, then drive the seal in evenly on the outer ring, never on the lip. If the shaft itself is worn, a repair sleeve is worth considering.
