The DBH 9984 oil seal is a single-lip radial shaft seal with a metal case, designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions are 80 mm shaft diameter, 140 mm housing diameter and 12 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment where the shaft passage through the housing must be sealed. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal.

This item is a DBH radial shaft seal, part number 9984, with the following dimensions: shaft diameter 80 mm, housing diameter 140 mm and height 12 mm. The Lx design corresponds to a single-lip seal with an outer metal case, with no additional spring visible in the designation. The DBH series is manufactured in elastomers resistant to mineral oils and greases, with a steel case for fitting into the housing. It is a wear part that is replaced when lubricant leakage or dirt ingress appears.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all cases it serves to confine the oil inside the assembly and prevent dust, water or particles from entering the bearing or gear. It is also used as a secondary closure on fan and industrial mixer shafts.

To install a seal, verify that the shaft has no burrs or wear in the contact area, and that the housing is clean and free of deformation. The lip must be lubricated before insertion, and the installation tool must press on the metal case, never on the lip. Selection depends on shaft speed, operating temperature and the type of fluid to be retained. If the shaft has a deep groove, consider a seal with an offset lip or a repair sleeve.

If you need an equivalent or a nearby size, send us part number 9984 along with the shaft, housing and height dimensions. A photo of the old seal or the full designation stamped on the part is also helpful. With that data we look for alternatives in other brands or series that MR carries, respecting housing tolerances. If space allows, we can offer you a seal with a similar design but a different material according to the fluid.
