The DBH 9520 radial shaft seal is a lip seal that mounts on a 50 mm shaft and in a 92 mm housing, with a height of 8 mm. Its Lx design combines a sealing lip and a dust lip, which improves protection against dust and dirt. It is used in gearboxes, pumps, electric motors and industrial equipment to retain lubricant and prevent contaminants from entering. MR Accesorios Industriales sells it as part of its line of seals and oil seals.

This item is a radial shaft seal from the DBH brand, identified with the code 9520. Its dimensions are: shaft diameter 50 mm, housing diameter 92 mm and height 8.00 mm. The Lx design indicates that it has a main sealing lip and a secondary exclusion lip, intended for environments with dust or particles. The inner lip runs on the shaft, while the outer lip acts as a barrier against contaminants. The manufacturer's commercial designation is 9520 and it corresponds to a radial seal, not an axial one.

Typical applications for this oil seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and transmission equipment. In all cases, the function is to retain the oil or grease inside the assembly and prevent external agents such as water, dust or chips from entering. It is also used in agricultural machinery, materials handling equipment and hydraulic systems where the shaft rotates at moderate speeds and sealing is critical to the service life of bearings and gears.

For mounting, check that the shaft has the appropriate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Seal selection must take into account rotation speed, working temperature and the type of fluid to be retained. If the seal is installed with the lip facing inward, it seals against the internal lubricant; if oriented the other way, it protects against external contaminants. In the Lx design, the dust lip must always face the dirty side.
