It is used in pumps, motors, gearboxes and equipment that requires a reliable, low-maintenance seal.

This item is a radial shaft seal from the DBH brand, identified with code 1337. According to the product page data, it has a housing bore diameter of 50 mm and a height of 8.00 mm. The indicated design is A 378, which defines the geometry of the lip and the metal body.

Typical applications of a seal such as the DBH 1337 include centrifugal pumps, electric motors, gearboxes, compressors and power transmission equipment. In all cases it fulfills the function of retaining the oil or grease inside the assembly and blocking the passage of dirt from the outside. It is also used on fan, mixer and conveyor shafts, where the environment may contain dust or moisture. The selection of the lip and spring material depends on the temperature and the fluid to be sealed.

To install a radial shaft seal, check that the housing is clean, free of burrs and with the correct tolerance. The lip must be lubricated before inserting the shaft, and the installation tool must rest on the outer edge so as not to damage the seal. It is important that the shaft has no splines or marks in the contact area. If the seal replaces another, compare the housing diameter, the height and the type of design; if in doubt, consult us with the shaft and housing measurements.
