This item is a DBH 5711 radial shaft seal, with A 039 design. Its dimensions are 50.80 mm shaft diameter (d), 81.00 mm housing diameter (D) and 17.85 mm height (h). The A 039 design corresponds to a single-lip seal with a spring, suitable for rotating shafts with lubrication. The 5711 nomenclature identifies the exact size within the DBH line, and is key to replacing the worn seal without errors.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases, its function is to retain the lubricant inside the assembly and block dust, water or particles that could damage bearings and gears. It is a wear part that should be replaced when leaks or abnormal noises appear in the seal area.

To install the seal correctly, check that the shaft is clean, free of burrs and marks, and that the sealing surface has the appropriate roughness. Lubricate the lip with compatible grease before inserting it and place the seal perpendicular to the shaft, without striking it directly. If the housing shows wear, consider using a seal with a larger outer diameter or a repair sleeve. The selection depends on the speed, temperature and type of lubricant of the equipment.
