The DBH 9411 is a radial shaft seal with a 40 mm shaft diameter, 70 mm housing diameter, and 8 mm height. It keeps lubricant in and contaminants out of rotating equipment, protecting bearings and bushings from premature wear. This seal is commonly found in gearboxes, pumps, motors, and other transmission assemblies.

The DBH 9411 features an Lx design: a sealing lip with a metal case that presses into the housing. The elastomer lip resists mineral oils and greases, while an internal spring maintains contact pressure on the shaft to accommodate minor eccentricity. The nominal dimensions are shaft 40 mm, housing 70 mm, and height 8 mm.

Use this seal on rotating shafts where lubricant containment and contaminant exclusion are required. Typical equipment includes gearboxes, centrifugal pumps, electric motors, mixers, conveyors, and agricultural or industrial machinery. The seal works alongside bearings or bushings, and correct selection helps prevent leaks and extend assembly life.

During installation, check that the shaft surface is free of burrs and has adequate hardness and finish. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in perpendicular to the shaft using a mounting tube or press. If the housing is worn, consider a seal with a larger outer diameter or a repair sleeve.
