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 seal is required. It is press-fitted into the housing and runs against the shaft, with a lip that maintains dynamic contact. It is a wear part: it should be replaced when oil leakage or dirt ingress appears.

This item is a radial shaft seal from the DBH brand, identified with the 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 code nomenclature makes it quick to locate in the catalogue and compare with other alternatives in the same family. It is a standard component within the seals and radial shaft seals that MR Accesorios Industriales sells.

Typical applications for a radial shaft seal of these dimensions include centrifugal pumps, electric motors, gear 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 the shaft. It is also used in machine tools, agitators and process equipment where the shaft rotates continuously and sealing is critical to bearing service life.

To correctly select a radial shaft seal, check 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 so as not to damage it. If the shaft shows a groove or wear, consider a repair sleeve before fitting the new seal.

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