The DBH 5128 radial shaft seal is a lip seal that is mounted in the housing and seals against the shaft to retain lubricant and block the entry of dust, water or particles. With dimensions of 48 mm shaft, 72 mm housing and 7.00 mm height, and Lx design, it is a common replacement part in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

The DBH 5128 is a radial lip seal with the following dimensions: shaft diameter 48 mm, housing diameter 72 mm and height 7.00 mm. Its Lx design indicates a specific construction within the radial shaft seal category. The flexible lip, generally made of elastomer, runs on the rotating shaft, while the outer body fits into the housing to maintain sealing. It is a wear part that is replaced when lubricant leakage or contaminant ingress appears.

This type of oil seal is used in equipment where a shaft rotates inside a lubricated housing: gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission systems. It also appears in applications exposed to dust or water, where the seal must prevent the contaminant from reaching the bearing or the lubricated area. Its 48 x 72 x 7 mm size makes it suitable for standard housings where a compact, thin-section seal is required.

To install an oil seal, check that the shaft has no burrs or wear, and that the housing is clean and free of deformation. It is advisable to lubricate the lip before inserting it and to use an installation tool that bears on the outer edge, never on the lip. The selection depends on shaft speed, working temperature and the fluid to be retained; if the original oil seal has a different design, compatibility must be confirmed with the manufacturer. Poor alignment or a scratched shaft shorten the life of the seal.
