The DBH 5163Sil radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to contain lubricant and stop 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 that operate 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 specific to the series; to confirm details of the lip, spring or material, consult the manufacturer's technical data sheet. The 5163Sil designation is the reference you will use to order it or to look for a nearby size.

Typical applications for a seal of these dimensions are centrifugal pump shafts, electric motors, reducers, rollers and transmission equipment. In all cases it serves the same function: retaining 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 install it properly, the shaft must be clean, free of burrs and marks, and the housing free of deformation. It is best to lubricate the lip before inserting it and to use an installation tool that presses on the outer edge, never on the lip. Selection depends on shaft speed, operating temperature and the fluid to be retained; with that data the lip and body material are determined. If the shaft shows wear, consider a nearby size or a repair sleeve.

If you need an equivalent or a different size, send code 5163Sil together with the shaft, housing and height dimensions, and the type of fluid and operating temperature. With that, we look for the alternative within the DBH line or other brands that MR carries. 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 carries the DBH brand as part of its line of seals and oil seals, along with bearings, power transmission and lubricants.
