The DBH 5490 radial shaft seal is a lip seal that mounts on the shaft and closes the passage of lubricant and contaminants in gearboxes, pumps and rotating equipment. Its Lz design combines a sealing lip with a dust lip, which makes it suitable for environments with dust or dirt. With 38.10 mm shaft diameter, 63.55 mm housing and 9.52 mm height, it is a frequently replaced size in industrial equipment.

This item is a radial shaft seal from the DBH line, identified with the part number 5490. Its dimensions are 38.10 mm shaft diameter (d), 63.55 mm housing diameter (D) and 9.52 mm height (h). The Lz design indicates a double-lip configuration: the main lip retains the oil and the secondary one acts as a dust lip, protecting the sealing area from the entry of particles. The elastomer is combined with an outer metal ring that guarantees the fit in the housing.

It is used on input and output shafts of gearboxes, centrifugal pumps, mixers, conveyors and transmission equipment in general. It also appears in agricultural machinery, industrial washing equipment and pumping systems where there is exposure to dust or water. Having a 38.10 mm shaft diameter, it is a common size in equipment of European and American origin, which makes it a frequently requested spare part.

For installation, check that the shaft has the appropriate hardness and surface finish, and that the housing is clean and free of burrs. Lubricate the lip before inserting the seal and do it with an installation tool that presses on the outer diameter, never on the lip. If the equipment works with a lot of vibration or misalignment, evaluate a design with greater rigidity or an additional lip. The final selection depends on speed, temperature and the fluid to be retained.
