A radial shaft seal in the DBH line, part number 8473, keeps lubricant where it belongs and keeps dust, water and other contaminants out of the assembly. It fits a 68 mm shaft, a 90 mm housing bore and a 10 mm height, and it uses the Kx design. You will find it on gearboxes, pumps, electric motors and other power transmission equipment that runs on oil or grease and needs a dependable barrier where the shaft exits the housing.

Reading the designation is straightforward: 8473 is the part number, and the three figures that follow describe the fit. Shaft 68 mm, housing 90 mm, height 10 mm, with the Kx lip and body configuration. Treat it as a wear part: once lubricant starts weeping past the lip or contaminants work their way in, the seal is swapped for another with the same designation.

Seals in this size range turn up on medium-section shafts. Gearboxes, centrifugal pumps, electric motors, rollers, and belt or chain drives are common homes for them. The job never changes: hold the lubricant in and keep the surrounding environment away from bearings and gears. Some plants also use this size as a secondary closure where oil splashes or where dust and moisture are present at moderate levels.

Installation rewards a little care. The shaft and housing should be clean, with no burrs or deep marks, and the lip gets a film of lubricant before it goes in. Seat the seal square to the bore and drive it with a tube or spacer that presses on the metal body, never directly on the lip. When you pick a replacement, match all four values: shaft diameter, housing diameter, height and design. Change any one of them and both the fit and the sealing behavior change with it.

Our team checks the dimensional match and the design, then comes back with options from the DBH line and help choosing between them.
