The DBH 9458 is a radial shaft seal that keeps oil, grease, and contaminants from passing between a rotating shaft and its housing. Its Lx design pairs a sealing lip with a metal outer body that presses into the housing bore. With a 56 mm shaft, 72 mm housing, and 8 mm height, it is a common replacement part in gearboxes, pumps, and other rotating equipment.

The seal carries designation 9458 and belongs to the DBH line. Its dimensions are shaft 56.00 mm, housing 72.00 mm, and height 8.00 mm. The Lx design denotes a single lip with a spring, suited to rotating shafts that run with lubrication. The metal outer body seats under pressure in the housing, while the lip rides on the shaft to form a continuous dynamic seal.

You will find this seal in gearboxes, reducers, centrifugal pumps, electric motors, drive shafts, and process equipment with rotating shafts. It also appears in agricultural machinery and materials handling equipment, and in industrial, food, and water treatment plants as a maintenance spare. It serves two purposes: holding lubricant inside the assembly and keeping the environment out of the bearing or gear area.

When selecting a replacement, confirm that the shaft diameter, housing diameter, and height match the dimensions of the original part. The shaft surface should be clean, free of burrs and deep marks, and the lip should be lubricated before insertion. Use the proper tool and apply uniform pressure on the metal body, never on the lip. If the shaft shows wear, a seal with the lip in a different position may be considered. Correct alignment between shaft and housing helps prevent premature leaks.
