The DBH 8166 radial shaft seal is a lip seal mounted in housings to retain lubricant and block the entry of dust, water or particles in equipment with a rotating shaft. Its designation 8166 corresponds to a size of 17 mm shaft diameter, 35 mm housing diameter and 7 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and similar mechanisms where bearings and gears must be protected.
This item is a DBH 8166 radial shaft seal, identified by its part number 8166. According to the product page data, it has a shaft diameter (d) of 17 mm, a housing diameter (D) of 35 mm and a height (h) of 7.00 mm. The Lx design indicates a specific construction of the lip and outer body, which defines how it seats in the housing and how it seals against the shaft. It is a precision component that works in dynamic contact with the shaft surface.
Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, compressors, transmission shafts and power transmission equipment in general. In all cases it fulfills the function of retaining oil or grease inside the assembly and preventing the entry of external contaminants, extending the service life of bearings, bushings and gears. It is also used in machine tools, process equipment and industrial assemblies where radial space is limited.
To correctly select a seal, you must verify that the shaft, housing and height dimensions match those of the machine's housing and shaft. The shaft surface must be in good condition, free of scratches and wear, and the housing must be clean and free of burrs. During installation, it is recommended to lubricate the lip with the same oil or grease used in service, use an installation tool that does not damage the lip, and verify that the seal sits perfectly perpendicular to the shaft. Forced or off-center installation causes premature leaks.
If you need a seal equivalent to the DBH 8166 or a nearby size, the most practical approach is to send us the complete part number, the shaft, housing and height dimensions, and a photo or sample of the original seal. With that data we can look for the alternative in our seal and oil seal line, or confirm whether there is an immediate larger or smaller size. We can also advise you on the most suitable lip design according to the type of lubricant and the working conditions.
