The DBH 5163Sil radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 25 mm shaft, 45 mm housing and 10 mm height place it in medium-sized equipment, where axial space is limited. It is used in pumps, electric motors, gearboxes and transmissions running with continuous rotation.

This item is a radial shaft seal from the DBH line, identified as 5163Sil. Its published attributes are: shaft diameter 25 mm, housing diameter 45 mm, height 10 mm and Lz design. The Lz design corresponds to a seal with a sealing lip and a construction configuration specific to the series; to confirm details of the lip, the spring or the material, consult the manufacturer's data sheet. The designation 5163Sil is the reference you will use to order it.

Typical applications of a seal of these dimensions are shafts of centrifugal pumps, electric motors, gearboxes, rollers and transmission equipment. In all cases it performs the same function: retaining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is also found in agricultural machinery, washing equipment and process lines where the shaft rotates continuously and there is exposure to dust or moisture.

To mount it properly, the shaft must be clean, free of burrs and marks, and the housing free of deformation. It is advisable to lubricate the lip before inserting it and to use a mounting tool that presses on the outer edge, never on the lip. Selection depends on shaft speed, working temperature and the fluid to be retained; with that data the lip and body material are defined. If the shaft shows wear, consider a repair sleeve.

If you need an equivalent or a different size, send the code 5163Sil together with the shaft, housing and height dimensions, and the type of fluid and working temperature. With that, the alternative is found within the DBH line or other brands MR sells. If space allows, a seal with a slightly different height or diameter can also be considered, as long as the housing and shaft accept it.

MR Accesorios Industriales sells the DBH brand as part of its line of seals and oil seals, along with bearings, power transmission and lubricants.
