The DBH 5442Sil radial shaft seal is a lip seal mounted between a rotating shaft and its housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 150 mm shaft, 180 mm housing and 13 mm height place it in medium to large equipment. It is used in gearboxes, pumps, electric motors and process machinery where reliable sealing prevents downtime and oil loss.

This DBH 5442Sil oil seal has a 150 mm shaft diameter, a 180 mm housing diameter and a 13.00 mm height, with Lx design. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with permanent lubrication. The 5442Sil nomenclature identifies the part within the DBH line and allows ordering it without ambiguity. Before mounting, check that the shaft has no burrs or marks and that the housing is clean and free of deformation.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, large electric motors, mixers and transmission equipment. In all cases it performs two functions: retaining the oil or grease inside the assembly and blocking the entry of external contaminants. When the equipment operates with high vibration or temperature, it is advisable to check the condition of the lip and spring before each scheduled shutdown.

To correctly select a radial shaft seal, the three dimensions must be respected: shaft diameter, housing diameter and height. Rotation speed, service temperature and type of lubricant also influence the choice. The Lx design is suitable for shafts with continuous rotation and oil lubrication. During mounting, lubricate the lip before inserting it, seat the part perpendicular to the shaft and use a tube or press that pushes on the outer ring, never on the lip.

If you need a nearby size or an equivalent from another brand, send us the code 5442Sil together with the shaft, housing and height dimensions. A photo of the old part or the housing drawing also works. With that data we review alternatives within the DBH line or from other brands we carry. Remember that shaft and housing tolerances are as important as the nominal dimensions of the seal.
