The DBH 5458 radial shaft seal is a lip seal mounted on the shaft to retain lubricant and block the entry of dust, water or particles. With dimensions of 68 mm shaft, 90 mm housing and 13 mm height, and Lz design, it is a common replacement part in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales sells it and quotes it on WhatsApp with code 5458.

The DBH 5458 is a radial shaft seal with 68 mm shaft diameter, 90 mm housing diameter and 13.00 mm height, with Lz design. The Lz design corresponds to a seal with sealing lip and spring, intended for rotating shafts with lubrication. The 5458 nomenclature identifies the exact size within the DBH line. Before mounting it, verify that the shaft and housing match these three dimensions: any difference of tenths can prevent the lip from seating properly or the part from fitting into its housing.

This type of seal is used in equipment where a shaft rotates inside a housing with oil or grease: gearboxes, centrifugal pumps, electric motors, rollers and conveyors. Its function is twofold: it prevents lubricant from escaping outward and dust or water from entering the bearing or gear. In food, aggregate or water treatment plants, where there is washing or a humid environment, the seal is a critical barrier for bearing service life.

To select a seal, the shaft diameter alone is not enough: the housing diameter and height must be respected, and the lip design must be chosen according to the direction of rotation and the type of lubricant. The Lz design is for general use on rotating shafts with lubrication. During mounting, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and tap it with a tube of suitable diameter, never with a screwdriver. A lip mounted crooked or dry fails within a few hours.

To quote for the 5458, send us the shaft diameter, housing diameter and height on WhatsApp, plus a photo of the old seal if you have it at hand. With that data we look for the equivalent in DBH or in another brand we sell. We can also advise you if the housing is worn or if the shaft has burrs, because in those cases it is worth evaluating a seal with a sleeve or a prior repair.
