The DBH 5256Pol radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. With a 25 mm shaft diameter, 35 mm housing diameter and 7 mm height, and Lz design, it is a compact size commonly found in power transmission equipment and small pumps. MR Accesorios Industriales carries it as part of its seals and oil seals line.

The DBH 5256Pol is a single-lip radial shaft seal. Its dimensions are shaft (d) 25 mm, housing (D) 35 mm and height (h) 7.00 mm. The Lz design indicates a lip configuration with spring, suitable for rotating shafts with lubrication. It is made of elastomer with metal reinforcement, although the specific properties of the compound are confirmed against the manufacturer's data sheet. It is a direct replacement part for standard 35 mm housings.

It is used in gearboxes, centrifugal pumps, electric motors, mixers and power transmission equipment. It also appears in machine tools, compressors and roller systems where oil or grease must be separated from the environment. Due to its size, it is common in low and medium power equipment, and in applications where axial space is limited. If the equipment operates with a lot of dirt or water, an additional lip or an external guard should be evaluated.

For installation, verify that the shaft has the proper hardness and surface finish, without burrs or marks. Lubricate the lip before sliding it on and use an installation tool that presses on the outer diameter, never on the lip. The seal must sit square with the housing. If the shaft shows wear, a repair sleeve can be a solution. Selection depends on speed, temperature and the fluid to be retained; with that data the compound and lip type are chosen.

If you need a nearby size or an equivalent, send us the full part number, the shaft, housing and height dimensions, and a photo of the old seal if possible. With that we review alternatives in the same series or in other brands we carry. We can also advise you if the Lz design is not the right one for your application and a different lip profile is needed.
