The DBH 8432/85 is a radial lip seal that sits in a housing and presses against a rotating shaft, keeping lubricant in and contaminants out. You will find it in gearboxes, pumps, motors and other power transmission assemblies where a shaft turns inside a fixed bore. With a 20 mm shaft, 35.90 mm housing and 9.60 mm height, it falls into the compact, general-purpose range.

This seal belongs to the DBH line and carries the code 8432/85 with design A 119. The dimensions are shaft 20 mm, housing 35.90 mm and height 9.60 mm. It is a single-lip seal with a metal case and elastomer, intended for rotating shafts with permanent lubrication. The code and design A 119 describe the lip and case geometry, so keeping them unchanged is the safest approach when you look for a replacement.

Seals of this size often appear in small gearboxes, centrifugal pumps, low-power electric motors, rollers and transmission shafts. They also show up in food, chemical and process equipment where oil or grease has to stay inside and dust or water has to stay outside. Because the shaft size is 20 mm, the seal fits compact machines and assemblies with limited radial space.

For a correct installation, make sure the shaft is clean and free of burrs or marks, and that the surface under the lip has a fine finish. Put some lubricant on the lip before you push the seal in, and keep it square to the shaft instead of tapping it from one side. When you choose a replacement, check shaft diameter, housing diameter, height and lip design: if any of those changes, the seal may not close properly or may not seat in the housing.

If you need an equivalent, send the code 8432/85 along with the shaft, housing and height dimensions, plus a photo or sketch of the seat. With that information we can search for an alternative in the DBH line or among other brands we supply. We can also tell you whether design A 119 is the right choice for your application or whether a different lip type or material would work better.
