The DBH 5173 is a radial shaft seal built to the Lx design, with a metal outer case and a sealing lip. Its dimensions are shaft 35 mm, housing 55.25 mm and height 10 mm. In service it holds lubricant inside the assembly and keeps dust, water and particles out of rotating equipment. Because the lip and the running surface wear over time, a seal that starts weeping oil is usually telling you the surface is scored or the lip has lost its elasticity. We supply this brand and can help you confirm the right replacement.

Reading the code is straightforward: 35 mm is the shaft it rides on, 55.25 mm is the bore it presses into, and 10 mm is the height. The Lx design means a lip seal with a metal body, press-fitted into the housing so the lip bears against the rotating shaft. This size shows up in gearboxes, pumps and medium-sized electric motors. Measure both the shaft and the housing with a caliper before ordering, since a few tenths of a millimeter change the fit.

You will find it on gearbox input and output shafts, centrifugal pumps, electric motors, mixers and transmission equipment. The job is always the same: retain the lubricant and block contaminants. Agricultural machinery and process equipment exposed to dust or water also use it. Where vibration or temperature runs high, check the lip compound against the manufacturer's data sheet before you commit.

Installation calls for a clean housing and shaft, no burrs or wear marks, and a lubricated lip. Seat the seal perpendicular to the shaft using a tube of the correct diameter; never drive it in by hitting the lip. The 10 mm height leaves little room for error, so the seat must be clean and free of deformation. A shaft with a worn running surface may not seal even with a correctly sized seal, and in that case a new shaft is the answer.

If code 5173 is not marked on your equipment, send the shaft, housing and height measurements along with the equipment brand. From that we can look for an equivalent in the same series. We can also advise on a version with an additional lip or a different material depending on the fluid involved. The more complete the details, the faster we can come back with a reliable option.
