The DBH 9854 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and stop dust, water or particles from entering. Its Lx design and dimensions of 55 mm shaft, 85.80 mm housing and 12 mm height place it in equipment with medium-size shafts. It is used in gearboxes, pumps, electric motors and transmissions where the seal runs at moderate speed with permanent lubrication.

This item is a DBH 9854 radial shaft seal, identified by its designation 9854. Its dimensions are 55 mm shaft diameter, 85.80 mm housing diameter and 12.00 mm height. The Lx design indicates the lip and metal case configuration, intended for rigid housings and finely finished shafts. The elastomer lip seals against the rotating shaft, while the outer diameter maintains the fit in the housing. It is a direct replacement part for equipment already using this size.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, induction electric motors, transmission shafts and continuous process equipment. In all cases it performs two functions: retaining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is also found in machine tools, compressors and material handling equipment where the shaft rotates at medium speeds and the working temperature is moderate.

To install a radial shaft seal, check that the shaft has no burrs, splines or wear in the contact area, and that the housing is clean and free of deformation. Lubricate the lip before inserting it and press it in with a tube of the correct diameter, without striking the metal case. Selection is defined by the three dimensions — shaft, housing and height — and by the lip design, which must be compatible with the speed, pressure and type of lubricant of the equipment.

If you need an equivalent or a nearby size, send us the code 9854 along with the shaft, housing and height dimensions, and a photo or sample of the original seal. With that data we review alternatives within the same seal category and confirm the option that fits best. We can also advise you if the housing has a shoulder or if the shaft shows wear and a repair size should be considered.
