The DBH 9916Pol is a radial shaft seal from the DBH line, built to keep lubricant in and contaminants out of rotating equipment. It fits a 48 mm shaft, a 60 mm housing bore, and a 21 mm width, and it uses the LMx-R H design, which combines a sealing lip with a dust lip. You will find this seal in gearboxes, pumps, motors, and similar machinery where a rotating shaft passes through a housing.

The part number breaks down into a few key pieces. The 9916Pol designation identifies the seal within the DBH series. The dimensions are shaft 48 mm, housing 60 mm, and width 21 mm. The LMx-R H profile means the seal has a main lip and an additional dust lip, so it handles moderate dust and splash exposure better than a single-lip seal. The elastomer is selected for resistance to industrial oils and greases, and the metal case holds its shape in the housing bore.

Typical applications include speed reducers, centrifugal pumps, electric motors, compressors, machine tools, and conveyors. The 48x60x21 size is common in medium-duty power transmission equipment, and it also appears in some automotive and agricultural assemblies. When a seal like this wears out, oil escapes and grit gets in, which speeds up wear on bearings and gears. Replacing it before that happens is a straightforward maintenance step.

Installation matters as much as the seal itself. Inspect the shaft for burrs, scratches, or a worn sealing surface, and make sure the housing bore is clean and round. Lubricate the lip with the same oil or grease used in the equipment. Use a proper installation sleeve or tube that presses on the outer diameter, never on the lip. The 21 mm width must match the housing depth. If the shaft has a groove from the old lip, a seal with the lip in a different position may be a better choice.
