The DBH 9779 is a radial shaft seal built to keep lubricant inside a rotating assembly and keep dust and water out. With a 53 mm shaft, a 69 mm housing bore and a 16 mm width, it fits common gearbox, pump, motor and transmission sizes. MR Industrial Accessories supplies this line and can help you match the seal to your equipment.

This seal belongs to the DBH range and carries the reference 9779. Read the three figures in order: shaft 53.00 mm, housing 69.00 mm, width 16.00 mm. The designation A 304 describes a single lip with a spring, which holds lubricant in and blocks contaminants during continuous running. Within the DBH catalog, 9779 is the code that ties those dimensions together.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. The lip rides on the shaft while the outer diameter seats in the housing bore, separating the lubricant side from the environment. Treat it as a wear item: once oil starts seeping out or grit works its way in, replacement is due.

Before ordering, confirm the shaft diameter falls within the recommended tolerance and that the surface is clean and free of burrs. The bore needs the right diameter and enough depth for the 16 mm width. Coat the lip with lubricant before pressing it in, keep the seal square, and avoid striking the lip during installation. If the shaft is already worn, a seal with the lip in a different position may work better.
