A radial shaft seal like the DBH 9791 keeps lubricant where it belongs and keeps dust and moisture out of the assembly. With a 29 mm shaft, a 43 mm housing bore and a 10.00 mm height, it fits spots where there is not much room along the shaft. MR Industrial Accessories supplies this brand and helps you match the right seal to the job.

The code 9791 belongs to the DBH line of radial shaft seals. The listing gives three figures you need to check before ordering: shaft 29 mm, housing 43 mm, height 10.00 mm. The Lx designation describes the build: a sealing lip combined with a metal case that presses into the bore. Parts like this show up regularly on maintenance schedules for rotating equipment.

Where does it go? Any place a shaft passes through a housing and the oil or grease has to stay inside: gear reducers, centrifugal pumps, electric motors, conveyor rollers, machine tool spindles. You will also find seals of this type on power transmission assemblies and on low-pressure hydraulic circuits. Two jobs at once, really: hold the lubricant in, and stop dust, water and grit from reaching the bearings and bushings.

Installation decides how long the seal lasts. Inspect the shaft first for nicks, burrs or a worn sealing track, and make sure the surface is clean and lightly oiled. Drive the seal in with a flat tool that contacts the outer diameter only, never the lip, and keep it square in the bore so it does not leak. When you pick a replacement, the three dimensions are the starting point, but also think about the fluid being sealed, the temperature in service and how fast the shaft turns.

If you need a cross-reference, send the code 9791 or simply the measurements you took from the old seal. With that we can look through the DBH range or find another seal that does the same job. Tell us too if the original had something extra, such as a second lip or a compound meant for higher temperatures, and we will factor that in.
