The DBH 9873/85 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants on rotating shafts. Due to its compact dimensions — 23.30 mm shaft, 29.70 mm housing and 4.00/6.00 mm height — it is used in equipment where axial space is limited and a reliable barrier against dust, water and particles is required. It is a wear part that should be replaced at the first sign of leakage.

This item is a seal from the DBH brand, identified by the designation 9873/85. Its dimensions are: shaft diameter 23.3 mm, housing diameter 29.7 mm and height 4.00/6.00 mm. The A 326 design corresponds to a single-lip configuration with a spring, intended for rotating shafts at moderate speeds. The variable height indicates that the seal can be mounted in housings with different depths within the indicated range, as long as the lip seat on the shaft is respected.

Typical applications of this seal include small gearboxes, electric motors, low-power centrifugal pumps, reducers and transmission equipment. It is also found in agricultural machinery, conveyors and lubrication systems where oil or grease must be contained and bearings protected from the environment. Due to its size, it is common in compact equipment or in positions where radial and axial space is limited.

To mount it correctly, verify that the shaft has no burrs or wear and that the sealing surface is clean and lubricated. The seal must enter perpendicular to the shaft, without impacts that deform the lip. If the housing has play or roughness, sealing can fail even if the dimensions are correct. When selecting, in addition to the dimensions, consider the type of fluid, the working temperature and the peripheral speed of the shaft.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the code 9873/85 or the current shaft and housing dimensions. With that data we can look for alternatives within the same category or from other brands we carry. We can also guide you if the A 326 design does not suit your application and another lip type or material should be evaluated.
