The DBH 8185 radial shaft seal is a lip seal that mounts on an 80 mm shaft and seals against a 110 mm housing, with a height of 10 mm. Its Lx design combines a sealing lip with a dust lip, which makes it suitable for retaining lubricant and excluding dust or dirt in rotating equipment. It is used in gearboxes, pumps, electric motors and transmissions where bearings must be protected and leaks prevented.

This item is a radial shaft seal from the DBH line, identified with part number 8185. According to the data sheet, it is designed for a shaft with a diameter of 80 mm, a housing of 110 mm and an overall width of 10 mm. The Lx design indicates that it has a main sealing lip and a secondary exclusion lip, mounted on a metal body that is press-fitted into the housing. It is a standard replacement part for rotating shafts with oil or grease lubrication.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. In all these cases, the seal performs two functions: retaining the lubricant inside the assembly and preventing the entry of external contaminants such as dust, water or particles. It is also found in machine tools, conveyors and continuous process equipment.

To correctly select a seal, you must verify the shaft and housing dimensions, the type of lubricant, the working temperature and the peripheral shaft speed. The Lx design is suitable when there is a risk of moderate external contamination. During installation, it is advisable to lubricate the lip, use an installation tool that does not damage the seal and ensure that the shaft has no burrs or splines. Eccentricity and axial play also affect the service life of the seal.

If you need an equivalent seal or a nearby size, the most practical thing is to send us the full part number, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can look for an alternative within the same DBH line or from other brands we carry. We can also advise you if the Lx design is not the most suitable for your application and it is worth evaluating another type of lip or material.
