The DBH 9825Pol is a radial shaft lip seal sized for a 27 mm shaft, a 37 mm housing bore and a 7.00 mm height. It keeps lubricant inside the housing and keeps dust, water and particles out where a rotating shaft passes through. MR Industrial Accessories supplies this seal within its seals and oil seals range for customers in the United States and Latin America.

The designation 9825Pol belongs to the DBH brand, and the construction profile shown for it is A 156-R-H: a lip seal with metal reinforcement and a geometry intended for oil retention on rotating shafts. Shaft diameter (d) is 27 mm, housing diameter (D) is 37 mm and height (h) is 7.00 mm. Because it is a wear part, its job is to hold the seal at the point where the shaft leaves the housing.

Typical installations include gearboxes, centrifugal pumps, electric motors, compressors, mixers and power transmission equipment, as well as fan shafts, conveyor rollers and machinery in agricultural or process plants. Anywhere a shaft turns through a cover or housing that contains lubricant, this type of seal serves two purposes: keeping the oil in and keeping contamination out.

Before fitting a replacement, inspect the shaft for burrs or wear and make sure the housing bore is clean and undistorted. Coat the lip with the same oil the equipment uses, then press the seal in with a tube that contacts the outer diameter only, never the lip. If the shaft shows a pronounced wear track, a seal with the lip in a different position may be worth considering. Lubricant type, temperature and shaft peripheral speed all affect selection.

To find an equivalent, share the full part number, the shaft, housing and height dimensions, and a photo of the old seal if you have one. With those details we can check alternatives in the same series or from other brands we carry, and advise whether the A 156-R-H profile suits your application or whether a different lip profile or material would work better.
