The DBH 8734 radial shaft seal is a lip seal designed for rotating shafts with a 20 mm diameter, a 47 mm housing bore and a 10 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in electric motors, pumps, gearboxes and power transmission equipment operating in workshops, plants and general maintenance.

This item is a radial shaft seal from the DBH brand, identified by the code 8734. Its dimensions are 20 mm shaft, 47 mm housing bore and 10 mm height. The Kz design corresponds to a configuration with a sealing lip and metal reinforcement, suitable for rotating shafts with lubrication. The elastomer lip runs on the shaft surface, while the outer diameter is fitted by interference in the housing. It is a precision part that must be installed without impacts or deformation.

Typical applications for this seal include low and medium power electric motors, centrifugal pumps, gearboxes, compressors and belt or chain drive equipment. It is also found in machine tools, conveyors and hydraulic systems where oil or grease must be contained. In all cases, the seal protects the bearings and extends the service life of the assembly, reducing downtime due to leaks or contamination.

To correctly select a seal, you must verify the shaft diameter, the housing bore diameter and the available height. The Kz design is suitable for moderate peripheral speeds and low pressures. During installation, lubricate the lip with the same oil or grease used in the equipment, insert the seal perpendicularly and avoid damaging the sealing edge. If the shaft shows wear or roughness, consider a repair sleeve or an alternative size.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the code 8734 or the current dimensions (shaft, housing bore and height). With that data we can look for a compatible alternative within our line of seals and oil seals. We can also advise you if the mounting space allows a different height or if the Kz design is not the most suitable for your application.
