This item is a DBH radial shaft seal, identified by code 5421. Its dimensions are 20.00 mm shaft diameter (d), 47.00 mm housing diameter (D) and 10.00 mm height (h). The Lx design corresponds to a single sealing lip with spring, intended for rotating shafts with lubrication. The lip elastomer and the metal body work together to maintain sealing under continuous service conditions.

Seals such as the DBH 5421 are used in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. Their function is twofold: prevent oil or grease leaks and block the entry of dust, water or particles. In industrial, food or process plants, this type of seal protects bearings and extends the service life of the assembly.

To install a radial shaft seal, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before inserting it and fit the seal with a press or suitable tool, never striking the lip. Selection depends on shaft speed, temperature and lubricant type. If the shaft has a worn track, consider a nearby size or a seal with an auxiliary lip.
