The DBH 9441 is a radial shaft seal built to close the gap between a rotating shaft and its housing, keeping lubricant in and contaminants out. With a 56 mm shaft diameter, an 82 mm housing diameter and an 8.00 mm height, it fits a wide range of power transmission and industrial machinery assemblies. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.

The DBH 9441 uses the Lx design: a single sealing lip with a spring, held in a metal body. The elastomer compound is formulated to resist mineral oils and greases, while the metal case holds the seal firmly in the housing bore. In code terms, the 56 mm figure refers to the shaft (d), the 82 mm figure to the housing bore (D) and the 8.00 mm figure to the height (h).

You will find this type of seal in gearboxes, pumps, electric motors, transmission shafts and continuous process equipment. Its job is to hold lubricant inside the assembly and block dust, water and particles that would otherwise shorten the life of bearings and gears. Because it is a wear part, it should be replaced once leakage or noise shows up around the seal area.

Before installation, confirm the shaft is free of burrs and wear and that the housing bore is clean and undeformed. Apply the same oil or grease used in the equipment to the lip, then seat the seal squarely. Shaft speed, operating temperature and the fluid being retained all influence seal selection. A deeply grooved shaft may call for a different size or a seal with an auxiliary lip.
