The DBH 9203Vit 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. Its Lx-R-H design combines a sealing lip with a spring that maintains even contact on the rotating shaft. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings and gears must be protected. MR Accesorios Industriales carries this official brand and helps you confirm the size before requesting a quote.

The DBH 9203Vit is a radial shaft seal with the following dimensions: shaft diameter 57 mm, housing diameter 71 mm and height 9.50 mm. The Lx-R-H design indicates a construction with a sealing lip, reinforced body and retaining spring, intended for rotating shafts with permanent lubrication. The lip runs on the shaft and the outer diameter fits into the housing, so the seal stays fixed while the shaft rotates. It is a wear part: when the lip hardens or gets marked, it starts to leak oil.

These seals appear in gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. They are also mounted on fan, mixer and conveyor shafts, where the environment has dust or moisture. The function is twofold: retain the lubricant inside the assembly and prevent contaminants from entering and damaging bearings, bushings or gears. In maintenance, the seal is often the part that gets replaced when an oil leak appears at the cover or the housing.

To mount a radial shaft seal, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before inserting it and seat the part fully perpendicular so it does not deform. If the shaft shows a deep groove, the new lip may not seal: in that case, consider a seal with an offset lip or repair the shaft. Selection is defined by the three dimensions — shaft, housing and height — and by the design type; if you have the old part, measure it with a caliper and compare it with the product page.
