The DBH 9787 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and stop the entry of dust, water or particles. Due to its dimensions of 26 mm shaft, 52 mm housing bore and 7 mm height, with Lx design, it is used in gear reducer boxes, pumps, electric motors and transmission equipment that run on shafts of that diameter. MR Accesorios Industriales sells it.

This item is a radial shaft seal from the DBH line, identified with the code 9787. Its dimensions are 26.00 mm shaft diameter, 52.00 mm housing bore diameter and 7.00 mm height, and its design is Lx. That set of dimensions defines the installation interference and the available axial space, so it is advisable to verify all three values before replacing a part. The sealing lip and the outer body work together: one seals on the shaft and the other secures in the housing.

Seals of this size appear in equipment where there is a rotating shaft exiting an oil or grease sump. They are commonly found in gear reducers and gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools. They are also used in applications where the environment has dust or moisture and the bearing or bushing behind the seal needs protection. In all those cases, the seal performs the dual function of retaining lubricant and excluding contaminants.

To select the correct seal, in addition to the dimensions, take into account the shaft speed, working temperature and type of fluid. A lip made of unsuitable material hardens or wears out prematurely. During installation, the shaft must be clean, with no burrs or marks, and it is advisable to lubricate the lip before inserting it. The seal sits perpendicular to the shaft and is driven to the bottom of the housing with a tube or spacer that bears on the outer ring, never on the lip.

If the 9787 code is not the one you need, or if the shaft or housing bore has another dimension, an equivalent can be found within the same radial shaft seal category. For that, send us the shaft diameter, housing bore diameter, height and, if you know it, the original designation of the equipment. With that data it is compared against the matching options and it is confirmed which one fits without modifying the installation.
