The DBH 5688 radial shaft seal is a lip seal designed to close the passage of oil or grease on rotating shafts and prevent dust and water from entering the mechanism. Due to its dimensions —47.63 mm shaft, 68.22 mm housing and 12.70 mm height— it is mounted in gearboxes, pumps, electric motors and power transmission equipment. It is a wear part: when lubricant loss or contaminant ingress appears, it is replaced with a new one.

This item is a radial shaft seal of the DBH brand, identified with the code 5688. Its dimensions are: shaft diameter 47.63 mm, housing diameter 68.22 mm and height 12.70 mm. The indicated design is Lz, which defines the geometry of the lip and the outer body. It is a single lip seal with spring, designed to retain lubricant on a shaft that rotates inside a cavity. The 5688 nomenclature follows the manufacturer's catalogue and must not be confused with inch dimensions or codes from other lines.

Typical applications of a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases it performs the same function: keeping the lubricant inside the assembly and blocking the entry of dust, water or particles that accelerate wear of bearings and gears. It is also used as a secondary closure in equipment where there is a pressure difference between the interior and the environment.

To install it correctly, check that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal with a tube or shim that rests on the outer body, never on the lip. The selection depends on the shaft speed, the working temperature and the type of lubricant; if those data are not defined, it is advisable to consult them with the supplier before ordering.

If you need a nearby size or an equivalent from another brand, send us the code 5688 or the three dimensions —shaft, housing and height— and the type of application. With that data we can locate the alternative within the DBH line or other brands we sell. We can also advise you if the original seal has a special design, such as double lip or reinforced metal body, so that the replacement is the correct one.
