The DBH 8185 is a radial shaft seal with an Lx design, meaning it has a main sealing lip plus a secondary dust lip. It fits a shaft of 80 mm, a housing of 110 mm and a width of 10 mm. This configuration keeps lubricant in and keeps dust and dirt out, which is why it is common in gearboxes, pumps, motors and transmissions where bearings need protection.

The seal belongs to the DBH line and carries part number 8185. Its dimensions are shaft 80 mm, housing 110 mm and overall width 10 mm. The Lx design uses a metal case that presses into the housing, with one lip for sealing and a second lip for exclusion. It is a standard replacement item for rotating shafts that run with oil or grease.

You will find this size in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. In each case the seal does two jobs: it holds the lubricant inside the assembly and blocks external contaminants such as dust, water or particles. Machine tools, conveyors and continuous process equipment also use it.

Selecting the right seal means checking shaft and housing dimensions, lubricant type, working temperature and peripheral shaft speed. The Lx design suits applications with moderate external contamination. During installation, lubricate the lip, use a tool that will not damage the seal, and make sure the shaft has no burrs or splines. Eccentricity and axial play also affect how long the seal lasts.

If you need an equivalent, send the full part number, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that information we can look for an alternative in the same DBH line or from other brands we supply. We can also tell you if the Lx design is not the best fit for your application and whether another lip type or material should be considered.
