The DBH 9155 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 40 mm shaft, 72 mm housing and 7 mm height place it in medium-sized transmission and rotating equipment. It is a wear part: when oil loss appears or dirt gets in, it is replaced. MR Accesorios Industriales sells it as an official brand.

The DBH 9155 is a seal with an Lx design, with a sealing lip and metal body. Its dimensions are 40.00 mm shaft diameter (d), 72.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design defines the geometry of the lip and the reinforcement, and it is the one that corresponds to this reference. It is press-fitted into the housing and works with the lip resting on the rotating shaft, usually with a spring that maintains contact pressure.

It is used in gearboxes, pumps, electric motors, transmission shafts, rollers and process equipment where there is a shaft rotating inside a housing and the lubricant needs to be separated from the environment. It also appears in applications with water or dust splash, where the seal prevents the contaminant from reaching the bearing or the gear. It is a critical part in equipment that cannot lose oil or allow dirt to enter.

To install it, check that the shaft is within tolerance and free of burrs, and that the housing has the correct diameter and depth. Lubricate the lip before installing and avoid hitting or deforming it. When selecting a replacement, take into account the shaft diameter, the housing diameter, the height, the lip design and the material, because a difference in any of those points changes the fit and the service life.
