The DBH 6784 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its standard dimensions —12.30 mm shaft diameter, 32.00 mm housing and 7.85 mm height— make it suitable for compact assemblies where axial space is limited. It is press-fitted into the housing and works against the shaft, creating a dynamic barrier that protects bearings, bushings and gears. It is a wear part: choosing the right compound and design extends the life of the assembly.

This item is a lip seal with designation 6784 from the DBH brand, with dimensions of 12.30 mm shaft diameter (d), 32.00 mm housing diameter (D) and 7.85 mm height (h). The indicated design is Lx, which corresponds to a seal with a sealing lip and standard configuration for rotating shafts. The lip works with slight interference on the shaft and a lubricant film that reduces wear. The outer casing is metallic, and the lip elastomer defines compatibility with the fluid and service temperature.

These seals are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil or grease must be contained and dust or water ingress prevented. They also appear in low-speed applications and in assemblies where the shaft does not show severe wear. As it is a frequently replaced part, it is advisable to identify the size and compound before disassembly, so as not to delay the repair.

To select correctly, verify that the shaft diameter is within the recommended tolerance for radial shaft seals and that the housing has the appropriate finish and hardness. Installation is done with a tool that presses on the outer edge, without hitting the lip, and with the spring facing the fluid to be retained. Lubricate the lip before inserting the shaft and avoid rotating the seal during installation. If the shaft has splines or burrs, protect the lip with a sleeve.

If you need a nearby size or an equivalent, send us part number 6784 or the shaft, housing and height dimensions. The original manufacturer's part number or a photo of the part also works. With that data we look for alternatives in the same series or in different compounds according to the fluid and operating temperature. If the seal is mounted on a bearing, we can review the complete assembly and suggest the most suitable seal.
