The DBH 5494 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in equipment with a rotating shaft. Its dimensions —56 mm shaft, 76.40 mm housing and 12.70 mm height— place it in medium-sized applications, where axial space is limited and a reliable closure is needed. It is press-fitted into the housing and works against the shaft, with a lip that maintains dynamic contact. It is a wear part: it should be replaced when oil loss or dirt ingress appears.

This item is a radial shaft seal from the DBH brand, identified by designation 5494. Its dimensions are 56 mm shaft diameter, 76.40 mm housing diameter and 12.70 mm height. The Lz design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The part number nomenclature allows it to be located quickly in the catalogue and compared with other alternatives in the same family. It is a standard component within the seals and oil seals supplied by MR Accesorios Industriales.

Typical applications for an oil seal of these dimensions include centrifugal pumps, electric motors, reducers, gearboxes and power transmission equipment. In all cases it performs two functions: retaining the oil or grease inside the assembly and preventing dust, water or particles from entering the bearing or shaft. It is also used in machine tools, agitators and process equipment where the shaft rotates continuously and sealing is critical to the service life of the bearings.

To select an oil seal correctly, verify the shaft and housing diameters with a caliper, and confirm the available height. The shaft surface must be ground and free of burrs; excessive roughness accelerates lip wear. When installing it, lubricate the lip with the same oil used in the equipment and use a support tube to avoid damaging it. If the shaft shows a groove or wear, consider a nearby size or a repair sleeve before fitting the new oil seal.

If you need an equivalent or a nearby size, the most practical approach is to send part number 5494 together with the dimensions measured on your equipment. You can also provide the number engraved on the old oil seal or the equipment manufacturer's designation. With that data, at MR Accesorios Industriales we compare it with the available alternatives and confirm whether there is a size that fits without modifying the housing. If space allows, an oil seal with a different height or a design with an additional lip can be considered.
