The DBH 9894 radial shaft seal is a single-lip component that fits onto a rotating shaft and into a housing cavity to keep lubricant in and contaminants out. With a shaft diameter of 56.5 mm, a housing bore of 79.45 mm and a height of 15.00/17.50 mm, it carries the A 348 design. This seal is a wear item, replaced when leakage or dirt ingress becomes apparent.

The designation 9894 identifies this DBH radial shaft seal. Its three key dimensions are shaft 56.5 mm, housing 79.45 mm, and overall width 15.00/17.50 mm. The dual height means the seal can sit in cavities of either depth while maintaining lip contact. The lip rotates against the shaft, while the outer case stays fixed in the housing to form the sealing barrier.

You will find this seal in gearboxes, pumps, electric motors, line shafts, and process equipment where rotation is continuous and oil or grease is present. It also suits environments with dust or water, where it serves two purposes: holding lubricant inside and limiting contaminant entry toward bearings or bushings. Maintenance teams often encounter it during scheduled rebuilds or when replacing failed seals on machines in service.

When selecting a replacement, confirm that the shaft and housing diameters match the values above. The 15.00/17.50 mm height allows installation in cavities within that range. Inspect the shaft surface for scratches or wear at the lip contact area, as these accelerate leakage. Lubricate the lip before installation and use a tool that will not damage it. If the shaft shows runout or eccentricity, consider an alternative with a reinforced lip.

For an equivalent seal, provide the code 9894 or the measured shaft and housing dimensions. We can search for alternatives within the DBH line or from other brands we supply, always checking against the manufacturer's data. We can also advise if the axial space differs or if the A 348 design does not fit your application.
