The DBH 9719 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With 47.70 mm shaft diameter, 72.95 mm housing bore and 12.00 mm height, and Kx design, it is used in gear reducer boxes, pumps and transmission equipment where lubricant must be retained and dust ingress stopped. MR Accesorios Industriales carries it as an official 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 bore 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 runs on the shaft and the metal case is press-fitted into the housing. It is a wear part: it is replaced when an oil leak appears or when the lip hardens or becomes damaged.

Typical applications for an oil seal of these dimensions are in gearboxes, gear reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases it performs the same function: keeping the lubricant inside the assembly and preventing contaminants such as dust, water or particles from entering. It is also used as a secondary seal 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 an oil seal, check the condition of the shaft: free of burrs, without wear and with adequate roughness for the lip. The housing must be clean and free of deformation, and the part is inserted perpendicular, with a suitable tool, without striking the lip. Before fitting it, lubricate the lip with the same oil used in the equipment. When selecting, verify that the d, D and h dimensions match those of the housing and shaft, and that the lip material is compatible with the fluid and the working temperature.
