The DBH 5163 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 25.00 mm shaft, 45.00 mm housing and 10.00 mm height place it in the range of compact general-purpose seals. It is used in pumps, electric motors, gearboxes and power transmission equipment where there is continuous rotation and a need to keep lubrication confined.

This item is a DBH radial shaft seal identified by code 5163. Its published attributes are: shaft diameter 25.00 mm, housing diameter 45.00 mm, height 10.00 mm and Lz design. The Lz design corresponds to a spring-loaded sealing lip that ensures contact on the shaft and compensates for small misalignments. The 5163 designation is the reference you will find on the manufacturer's product page and the one you should quote when asking for equivalents or replacements.

Typical applications for a seal of this size include electric motors, centrifugal pumps, gearboxes, reducers, compressors and belt- or chain-driven transmission equipment. In all these cases the seal serves two functions: preventing oil or grease from escaping to the outside and preventing dirt from entering the bearing or bushing. It is also used on fan, mixer and conveyor shafts where there is sustained rotation.

To select the correct seal, take into account the shaft diameter, housing diameter and available height. Check that the shaft surface is clean, free of burrs and marks, and that the housing has the proper chamfer so the lip is not damaged during installation. Lubricate the lip before inserting it and avoid striking it directly: it is best to use a tube or spacer that presses on the outer ring. If the equipment operates with high vibration or temperature, ask about material variants.

To quote code 5163 together with the shaft, housing and height dimensions shown on your equipment, send us. A photo of the old seal or the assembly drawing is also helpful. With that data we can look for an alternative within the same category or suggest a seal with a different lip design.
