The DBH 9155 is a radial shaft seal in an Lx design, built with a sealing lip and a metal body. It presses into the housing and the lip runs against the rotating shaft to hold lubricant in and keep dust, water and particles out. With a 40 mm shaft, a 72 mm housing bore and a 7 mm height, it fits medium-sized rotating equipment and transmissions. Like any seal, it is a wear part: once oil loss or contamination shows up, it gets replaced.

Read the reference by its dimensions first: shaft 40.00 mm, housing 72.00 mm, height 7.00 mm. The Lx designation describes the lip and reinforcement geometry, and it is the design tied to this code. A spring usually keeps the lip in contact with the shaft, so the seal stays loaded as the shaft turns.

You will find this size in gearboxes, pumps, electric motors, transmission shafts, rollers and process equipment where a shaft rotates inside a housing and the lubricant has to stay separated from the environment. It also suits spots with water or dust splash, keeping contaminants away from the bearing or gear. In equipment that cannot lose oil or take in dirt, the seal is a critical part.

Installation calls for a shaft within tolerance and free of burrs, plus a housing with the correct bore and depth. Lubricate the lip before pressing it in and avoid striking or deforming it. When picking a replacement, match shaft diameter, housing diameter, height, lip design and material, since a change in any one of them affects fit and service life.
