The DBH 9422 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its Lx design and dimensions of 50 mm shaft, 80 mm housing and 8 mm height make it suitable for equipment with medium-section shafts. It is used in pumps, electric motors, gearboxes and industrial transmissions.

The DBH 9422 is a radial shaft seal with an Lx design and the following dimensions: shaft diameter 50 mm, housing diameter 80 mm and height 8.00 mm. The sealing lip runs on the shaft and the outer case fits into the housing. The Lx designation indicates a specific construction within the DBH line, which you can confirm against the manufacturer's data sheet if you need details on the lip or the spring.

These seals are used in centrifugal pumps, electric motors, gearboxes, transmission shafts and process equipment. Their function is twofold: to prevent oil or grease leaks and to stop the entry of contaminants. In environments with dust, wash water or fine chips, a well-selected seal extends the life of bearings and gears. They are also used in applications where the shaft rotates at moderate speed and the temperature is not extreme.

For installation, check that the shaft is clean, free of burrs and marks, and that the housing is not dented. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The seal must go in perpendicular, without deforming the lip; use a tube or press that bears on the outer edge. If the shaft shows wear, consider a nearby size or a seal with an offset lip. Selection depends on speed, temperature and the fluid to be retained.
