The DBH 8239 is a radial shaft seal that fits into a housing and seals against a rotating shaft to keep lubricant in and contaminants out. Its Lx-R AH configuration includes a primary sealing lip and an additional dust lip, making it a practical choice for equipment that operates in moderately dirty conditions. You will find this seal in gearboxes, pumps, electric motors, and conveyor rollers, among other industrial machinery.
This DBH 8239 radial shaft seal is sized for a 148 mm shaft, a 170 mm housing bore, and a 15.00 mm height. The Lx-R AH designation tells you the seal has a main lip for fluid retention plus an auxiliary lip that helps block external contaminants. DBH is a brand we supply, and every order is checked against the manufacturer's data sheet using the 8239 code.
Seals of this size commonly appear in gear reducers, centrifugal pumps, electric motors, conveyor rollers, and transmission units. In each case, the seal sits in a stationary housing and runs against a rotating shaft, separating the lubricated side from the environment. It keeps oil or grease from escaping while also protecting bearings and bushings from dust, washdown water, or metal chips.
Proper installation starts with a clean shaft and housing, free of burrs or deep scratches, and a shaft surface with the right hardness and finish. Press the seal in squarely, without hammering that could distort the lip, and lubricate it before assembly. When selecting a replacement, consider shaft speed, operating temperature, and the fluid being sealed.

- What does the Lx-R AH design mean?
