The DBH 9787 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and keep out dust, water and particles. With its dimensions of 26 mm shaft, 52 mm housing and 7 mm height, in Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment running on shafts of that diameter. MR Accesorios Industriales supplies it as an official brand.

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

Seals of this size appear in equipment where a rotating shaft exits an oil- or grease-filled housing. 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 is dusty or humid and the bearing or bushing behind the seal needs protection. In all those cases, the seal serves the dual purpose of retaining lubricant and excluding contaminants.

To select the correct seal, in addition to the dimensions, take into account shaft speed, operating temperature and the type of fluid. A lip made of the wrong material hardens or wears out prematurely. During installation, the shaft must be clean, free of burrs and 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 sleeve that presses on the outer ring, never on the lip.

If part number 9787 is not the one you need, or if the shaft or housing has a different dimension, an equivalent or a nearby size can be found within the same radial shaft seal category. To do that, send us the shaft diameter, housing diameter, height and, if you know it, the original equipment designation. With that data we compare against the available alternatives and confirm which one fits without modifying the mounting.
