The DBH 5339Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain the lubricant inside the housing and prevent dust, water or contaminating particles from entering. With dimensions of 40 mm shaft, 56 mm housing and 8 mm height, and an Lx design, it is used in pumps, electric motors, gearboxes and industrial equipment in general. MR Accesorios Industriales sells this brand and advises you so that you choose the right seal for your application.

This item is a radial shaft seal of the DBH brand, identified with the part number 5339Pol. Its dimensions are: shaft diameter 40 mm, housing diameter 56 mm and height 8.00 mm. The Lx design corresponds to a seal with a sealing lip and spring, suitable for rotating shafts with lubrication. The lip is designed to work on the shaft and maintain sealing under continuous rotation conditions. It is important to verify that the dimensions match the housing and the shaft before installation.

The typical applications of this seal include centrifugal pumps, electric motors, speed reducers, compressors, machine tools and power transmission equipment. In all cases, the seal prevents oil or grease leaks and protects bearings and gears from the entry of contaminants. It is also used in agricultural and industrial equipment where reliable sealing is required on shafts that rotate at moderate speeds. The choice of lip and spring material depends on the fluid and the working temperature.

To mount this seal correctly, keep in mind that the shaft must be clean, free of burrs and scratches, and lubricated before inserting the seal. The housing must be machined with the appropriate tolerance and free of damage. It is recommended to use a mounting tool that rests on the outer diameter of the seal and not on the lip. If the shaft shows wear, evaluate the possibility of using a seal with an offset lip or a repair sleeve. Correct alignment between shaft and housing is essential to prevent premature leaks.
