The DBH 8637 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles. With dimensions of 35 mm shaft diameter, 49 mm housing and 12.50 mm height, it is press-fit into covers, boxes or pumps. It is a wear part that should be replaced at the slightest sign of leakage. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified with the code 8637. Its dimensions are 35.00 mm shaft diameter (d), 49.00 mm housing diameter (D) and 12.50 mm height (h). The Lx-R-AH design indicates a configuration with a retaining lip, spring and reinforced body for demanding applications. The sealing lip runs on the rotating shaft, while the outer diameter fits into the housing to ensure tightness.

It is used in equipment where there is rotary motion and a need to confine lubricant: gearboxes, centrifugal pumps, electric motors, transmission shafts, mixers and agricultural or industrial machinery. It also appears in applications exposed to dust or water, where the seal acts as a barrier. It is commonly found in plant maintenance, repair shops and production line replacements.

To mount it correctly, verify that the shaft has no burrs or wear and that the surface where the lip seats is clean and lubricated. The housing must be free of impacts and have the proper depth so that the seal sits flush or slightly recessed. When selecting a replacement, in addition to the dimensions, take into account the type of elastomer and the spring, depending on the temperature and the working fluid. Forced or off-center installation shortens service life.
