The DBH 5143 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 34 mm shaft diameter, 72 mm housing diameter and 14 mm height, and Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment to retain lubricant and stop dust or water from entering. MR Accesorios Industriales sells it.

This item is a DBH 5143 radial shaft seal, with the dimensions shown on its product page: 34 mm shaft diameter (d), 72 mm housing diameter (D) and 14.00 mm height (h). The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with internal lubrication. The designation 5143 identifies the exact size within the DBH line, so it is best to order it by that part number to avoid confusion with similar sizes.

Typical applications for a seal of this size are gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases it serves two functions: retaining the oil or grease on the lubricated side and preventing contaminants from entering from outside. It is a wear part, so it is replaced when a visible leak appears or when the lip hardens or becomes damaged.

To install it, check that the shaft is clean, free of burrs and machining marks, and that the surface where the lip seats has the right roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or press that bears on the metal edge, never on the lip. If the housing has a recess, respect the depth so the seal seats fully and does not sit crooked.
