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

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 code to avoid confusion with similar sizes.

Typical applications of a seal of this size are gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases it performs 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, verify that the shaft is clean, free of burrs or machining marks, and that the surface where the lip rests has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or press that rests on the metal edge, never on the lip. If the housing has a recess, respect the depth so that the seal seats completely and does not sit crooked.
