The DBH 8371 radial shaft seal is a lip seal mounted in the housing that closes against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. Its Lx design, with a single sealing lip and metal body, makes it suitable for rotating shafts in industrial equipment. MR Accesorios Industriales supplies this brand and advises you to choose the correct size for your application.

This item is a DBH 8371 radial shaft seal with the following dimensions: shaft diameter 42 mm, housing diameter 72 mm and height 10 mm. The Lx design corresponds to a single-lip seal with a metal case and elastomeric sealing lip, without an additional spring visible in the designation. It is a dynamic sealing component that works on the shaft and inside a machined cavity, retaining the oil or grease of the bearing and preventing external contamination.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, reducers, electric motors, transmission shafts and process equipment in industrial plants. It is also used in agricultural machinery, material handling equipment and lubrication systems where lubricant must be contained at one end of the shaft. Its function is to protect the bearings and extend the service life of the assembly, reducing leaks and wear.

To correctly install this oil seal, verify that the shaft has the appropriate hardness and roughness, without burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease as the equipment before inserting it, and place the seal perpendicular to the shaft using an installation tube that rests on the metal case, never on the lip. If the housing shows wear, evaluate the use of a seal with greater height or a repair sleeve. Selection must consider speed, temperature and type of fluid.

If you need an equivalent or a neighboring size, send us the complete code of the seal you are replacing, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for an alternative within the DBH line or from other brands we supply. We can also advise you if the Lx design is not the most suitable for your application and it is worth evaluating another type of lip or material.
