The DBH 1181Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent external contaminants such as dust or water from entering. With dimensions of 24.50 mm shaft diameter, 42.00 mm housing and 6.00 mm height, and an Lz-R H design, it is a common replacement part in industrial equipment. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

This DBH 1181Pol oil seal has a shaft diameter of 24.50 mm, a housing diameter of 42.00 mm and a height of 6.00 mm. The Lz-R H design indicates a configuration with a retaining lip and dust lip, intended for applications requiring additional protection against contamination. The designation 1181Pol identifies the size and construction type within the DBH line. It is a radial sealing component that works on rotating shafts, with the lip resting on the shaft surface and the body seated in the corresponding cavity.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. In general, they are mounted in assemblies where a shaft rotates inside a housing and oil or grease must be separated from the outside environment. They also appear in applications exposed to dust or splashes, where the dust lip of the Lz-R H design helps extend the service life of the main lip. They are wear parts that should be replaced during preventive maintenance tasks.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of the original component. Shaft tolerance and surface finish affect sealing: a scratched or worn shaft can cause leaks even if the seal is new. During mounting, lubricate the lip with the same oil or grease used in the equipment and avoid hitting or deforming it. If the housing has burrs, clean them before inserting the seal. Proper alignment between shaft and housing is also key to avoiding lateral stress on the lip.

If you need a seal with equivalent dimensions or a close variant, you can consult us. Sometimes a nearby size or an alternative design can adapt to the same housing, as long as functional tolerances are respected. For that, it is best to send us the original code, the measurements taken or a photo of the part. At MR Accesorios Industriales we evaluate alternatives within the brands we carry and advise you on the most convenient option for your equipment.
