The DBH 9900 is a radial shaft seal built to keep lubricant in and contaminants out of equipment with a rotating shaft. Its 68 mm shaft, 90 mm housing and 10 mm width suit medium-sized power transmission and machinery. MR Industrial Accessories supplies this brand and helps you match the seal to your application.

This seal belongs to the DBH line and carries code 9900. The Kz version has a sealing lip with metal reinforcement, so it holds oil or grease inside bearing chambers and gearboxes. Installation is a press fit into the housing, with the lip riding on the shaft. It works as a direct replacement part.

Sizes like these are common in gearboxes, centrifugal pumps, electric motors, speed reducers, and belt or chain drives. You will also find them in agricultural machinery, conveyors and hydraulic systems where leaks and outside contamination need to be controlled. When the shaft and housing are in good shape, the seal shields the bearings and supports the life of the assembly.

Before ordering, confirm the shaft measures 68 mm and the housing 90 mm, and that the mounting depth fits the 10 mm width. The Kz design calls for a smooth shaft without burrs and a housing finish suited to a press fit. Lubricate the lip at installation and use a tool that will not cut or distort the seal. If the shaft is worn, a repair sleeve or a different size may be the better route.

For an equivalent, send code 9900 or the dimensions of your equipment. We can check alternatives within the same DBH brand or other lines we carry, and advise whether the mounting space allows a different height or design. The more you share — diameters, width, lubricant type and operating conditions — the more precise the match.
