The DBH 5432 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 12.70 mm shaft, 25.37 mm housing and 6.35 mm height place it in compact applications, such as small gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this official brand and will quote it for you on WhatsApp.

This item is a DBH 5432 oil seal, a radial lip seal with the following dimensions: shaft diameter 12.70 mm, housing diameter 25.37 mm and height 6.35 mm. The Lx design corresponds to a single lip configuration with spring, intended for rotating shafts with lubrication. The 5432 designation identifies the exact size within the DBH line, and it is advisable to verify that it matches the housing and the shaft before replacing.

Seals of this size are used in equipment where radial space is limited: small electric motors, centrifugal pumps, worm gearboxes, fan shafts, machine tools and low-power transmission equipment. Their function is twofold: to prevent oil or grease leaks to the outside and to stop the entry of contaminants that wear down bearings and bushings. In these assemblies, the seal works alongside the bearing and defines a good part of the service life of the assembly.

Several points must be taken into account when selecting and mounting a seal. The shaft must be within the recommended tolerance, free of burrs and marks, and the housing must have the correct diameter and depth. Before installing it, lubricate the lip with the same oil or grease used in the equipment and use a mounting tool that presses on the outer edge, never on the lip. If the shaft shows wear, consider a neighboring size or a seal with the lip in a different position.

If you need an equivalent or a nearby size, send us part number 5432 together with the shaft, housing and height dimensions, plus a photo of the old seal if possible. With that data we review alternatives within the DBH line and other brands we carry. We can also advise you if the housing has a shoulder or if the original seal came with a configuration different from Lx.
