The DBH 8432/85 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a fixed body. Its dimensions of 20 mm shaft, 35.90 mm housing and 9.60 mm height place it in the range of compact general-purpose seals.

This item is a radial shaft seal from the DBH line, identified with the designation 8432/85 and design A 119. Its dimensions are 20 mm shaft diameter (d), 35.90 mm housing diameter (D) and 9.60 mm height (h). It is a single-lip seal with a metal case and elastomer, designed for rotating shafts with permanent lubrication. The designation and design A 119 define the geometry of the lip and the case, so it is best to respect them when looking for a replacement.

Typical applications for a seal of this size are small gearboxes, centrifugal pumps, low-power electric motors, rollers and transmission shafts. It also appears in equipment in the food, chemical and process industries, where oil or grease must be contained and contaminants kept out. Being a 20 mm shaft size, it is common in compact machines and in assemblies where radial space is limited.

To install it properly, check that the shaft is clean, free of burrs and marks, and that the surface where the lip rests has a fine finish. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it from the side. When selecting a replacement, take into account the shaft diameter, the housing diameter, the height and the lip design: changing any of those values can cause the seal not to close or not to fit in the seat.

If you need a nearby size or an equivalent, send us the code 8432/85 together with the shaft, housing and height dimensions, and a photo or sketch of the seat. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also advise you if design A 119 is not the right one for your application and a different type of lip or material is needed.
