The DBH 9825Pol 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. With a 27 mm shaft diameter, 37 mm housing diameter and 7 mm height, it is a compact size widely used in power transmission equipment, pumps and electric motors. MR Accesorios Industriales supplies it as a brand within its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, designation 9825Pol, with the following dimensions: shaft diameter (d) of 27 mm, housing diameter (D) of 37 mm and height (h) of 7.00 mm. The design indicated on the product page is A 156-R-H, which corresponds to a lip seal with metal reinforcement and a specific geometry for oil retention on rotating shafts. It is a wear component: its function is to maintain sealing at the point where the shaft exits the housing.

It is used in gearboxes, centrifugal pumps, electric motors, compressors, mixers and power transmission equipment in general. It also appears on fan shafts, conveyor rollers and agricultural or process machinery. Whenever a rotating shaft passes through a cover or housing with lubricant inside, this type of seal performs the dual function of retaining the oil and preventing external contamination.

For installation, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip with the same oil used in the equipment before inserting it, and install the seal with a support tube that pushes on the outer diameter, never on the lip. If the shaft shows a marked track, consider a seal with the lip in a different position. Selection depends on the type of lubricant, the temperature and the peripheral speed of the shaft.

If you need an equivalent, send us the complete part number, the shaft, housing and height dimensions, and a photo of the old seal if possible. With that data we can look for alternatives within the same series or from other brands we carry. We can also advise you if the A 156-R-H design is not the right one for your application and a different lip profile or material would be better.
