Typical applications of a seal such as the DBH 5109 include centrifugal pumps, electric motors, gearboxes and transmission equipment. In these assemblies, the seal prevents oil or grease leaks and blocks the entry of dust, water or particles. It is also used on fan and compressor shafts. Selection depends on shaft speed, working temperature and the type of lubricant. In each case, it is key to verify that the shaft diameter and housing match the indicated dimensions.

To correctly install a radial shaft seal, clean the housing and shaft, check that there are no burrs or scratches and lubricate the lip before inserting it. Use an installation tube or press to apply uniform force, avoiding direct blows on the lip. The 12.70 mm height should sit flush or slightly recessed depending on the housing design. If the shaft shows wear, consider a repair sleeve. Correct alignment between shaft and housing extends the service life of the seal.
