The DBH 5125 radial shaft seal is a lip seal that closes off the passage of oil and grease at the point where a shaft passes through a housing. With 70 mm shaft, 89 mm housing and 10 mm height, and Lz design, it is used in gearboxes, pumps and power transmission equipment where there is continuous rotation and contact with lubricant.

This item is a radial shaft seal from the DBH line, identified with part number 5125. Its dimensions are 70 mm shaft diameter (d), 89 mm housing diameter (D) and 10 mm height (h). The Lz design defines the geometry of the lip and the metal body, intended to retain lubricant and stop the entry of dust and water from the external side. It is a replacement part, not a component that adapts to any size: the shaft and housing must match those values.

Typical applications for a seal of this size appear in gear cases, gearboxes, centrifugal pumps, electric motors and power transmission equipment. In all those cases the seal works on a rotating shaft and against a fixed housing, separating the oil from the environment. It is also used in agricultural machinery, conveyors and process equipment where washing or dust require a reliable closure.

To mount it, check that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or shim that rests on the outer edge, never on the lip. If the shaft shows wear, evaluate a nearby size or a seal with an auxiliary lip before forcing the original part.

If you need an equivalent or a close size, send us part number 5125 along with the shaft, housing and height dimensions you have on the equipment. With that data we review alternatives within the same DBH line or from other brands we carry, and we confirm which option fits without modifying the housing. We can also verify the Lz design against the one the original equipment has.

MR Accesorios Industriales carries the DBH brand and has more than 80 years of experience in bearings, power transmission and seals.
