The DBH 5204Pol radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating equipment. It is installed between a rotating shaft and a stationary housing, and it runs on the shaft through a flexible lip. Because of its dimensions, it is used in gearboxes, pumps, motors and other assemblies where radial space is limited. MR Accesorios Industriales sells this brand as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH line, identified by the code 5204Pol. Its nominal dimensions are: shaft diameter 49.2 mm, housing diameter 65.06 mm and height 12.70 mm. The indicated design is Mz-R, which corresponds to a configuration with a sealing lip and a metal case. These dimensions define the mounting interference and must match the shaft and the housing to ensure an effective seal.

Radial shaft seals of this type are used in equipment with continuous rotation and the need to retain oil or grease. They appear in gearboxes, centrifugal pumps, electric motors, rollers and transmissions. They are also used in applications exposed to dust or water, where the lip acts as a barrier. The choice of lip material and spring depends on the temperature and the fluid to be retained, so it is advisable to verify that data before defining the replacement.

To install a seal, check the condition of the shaft: it must not have burrs, scratches or wear in the contact area. The housing must be clean and free of deformation. It is recommended to lubricate the lip before inserting it and to use an installation tool that presses on the outer diameter, never on the lip. The 12.70 mm height defines the required axial space. If the shaft has a worn track, a repair sleeve can be evaluated.

If you need a seal equivalent to the 5204Pol, the most practical approach is to send the code, the shaft, housing and height dimensions, and a photo of the part. With that data, an alternative can be found within the same DBH line or from other brands that MR sells. Seals with different lip configurations or materials can also be quoted according to the fluid and the working temperature.
