The DBH 8387/85 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. Due to its dimensions —19 mm shaft, 33.30 mm housing and 7.80 mm height— it is used in gearboxes, pumps, electric motors and power transmission equipment where lubricant must be retained and the entry of dust or water stopped. It is a wear part: when lubricant loss or contaminant entry appears, it is replaced.

This item is an oil seal from the DBH brand, code 8387/85, with the following dimensions: shaft diameter 19 mm, housing diameter 33.30 mm and height 7.80 mm. The indicated design is Lx, which corresponds to a single-lip seal with a spring, intended for rotating shafts with lubrication. The elastomeric lip bears on the shaft and the spring maintains contact pressure; the outer body is press-fitted into the housing. It is a standard radial sealing component, not a special part.

Typical applications for an oil seal of these dimensions are gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases it performs the same function: preventing oil or grease from escaping the assembly and dust, water or particles from entering the bearing or gear. It is also used on fan, mixer and conveyor shafts, where the working environment is demanding.

To install an oil seal, check that the shaft has no burrs, scratches or wear in the contact area, and that the housing is clean and free of deformation. The lip is lubricated before inserting it and it is seated perpendicular to the shaft. If the shaft shows a marked groove, it is advisable to consider a nearby size or an oil seal with the lip in another position. The selection depends on the speed, temperature and type of lubricant of the equipment.

If you need an equivalent or a close size, send us the code 8387/85 together with the shaft, housing and height dimensions, and the equipment brand.

The more precise the information, the faster we reach the correct part.
