The DBH 9719 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With 47.70 mm shaft diameter, 72.95 mm housing diameter and 12.00 mm height, and Kx design, it is used in gearboxes, pumps and transmission equipment where lubricant must be retained and the entry of dust blocked. MR Accesorios Industriales carries it as a brand.

This item is a DBH 9719 radial shaft seal, identified by its designation 9719. Its dimensions are 47.70 mm shaft diameter (d), 72.95 mm housing diameter (D) and 12.00 mm height (h). The Kx design corresponds to a lip and case configuration intended for lubricant retention on rotating shafts. The elastomeric lip works on the shaft and the metal case is press-fitted into the housing. It is a wear part: it is replaced when oil leakage appears or when the lip hardens or becomes damaged.

Typical applications for a seal of these dimensions are in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases it fulfills the same function: keep the lubricant inside the assembly and prevent contaminants such as dust, water or particles from entering. It is also used as a secondary closure on shafts that rotate at moderate speeds and with low differential pressure. If the equipment operates with a lot of dirt or frequent washing, it is advisable to evaluate a design with an additional dust lip.

To install a seal, you must check the condition of the shaft: no burrs, no wear and with the roughness suitable for the lip. The housing must be clean and free of deformation, and the part is inserted perpendicular, with the proper tool, without striking the lip. Before placing it, lubricate the lip with the same oil as the equipment. When selecting, verify that dimensions d, D and h match those of the housing and the shaft, and that the lip material is compatible with the fluid and the working temperature.

If you need an equivalent, send us code 9719 or the dimensions 47.70 x 72.95 x 12.00 mm and we will help you find the option that best suits you. We also tell you about the seal with the same shaft diameter and a different height, or with a design with a dust lip. The more data you send us —equipment, fluid, temperature and speed—, the more accurate the search. The idea is that you are not left with equipment stopped for a part that can be sourced.
