The DBH 8230 radial shaft seal is a single-lip seal designed for rotating shafts. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that could damage bearings and bushings. With dimensions of 15 mm shaft, 22 mm housing and 4.50 mm height, it is press-fitted into the cavity and runs on the shaft surface. It is a wear part that should be replaced when oil loss or play appears.

This DBH 8230 oil seal has a shaft diameter of 15 mm, a housing diameter of 22 mm and a height of 4.50 mm. The Ls design corresponds to a single lip with a spring, intended for applications where axial space is limited. The 8230 nomenclature identifies the exact size within the DBH line. It is a standard radial sealing component, not a special-type seal. It is fitted with interference in the housing and the lip rests on the shaft with slight pressure.

It is used in small electric motors, centrifugal pumps, reducers, gearboxes and power transmission equipment. It also appears in machine tools, compressors and lubrication systems where there is a rotating shaft that must be isolated. In the food and process industries it is selected according to the lip material, which must be compatible with the fluid and the working temperature. It is a critical part for the service life of the nearby bearings and bushings.

To install it, verify that the shaft has no burrs or marks and that the sealing surface is polished. Lubricate the lip before inserting it and fit the seal with a support tube that presses on the outer edge, never on the lip. The 4.50 mm height requires a cavity with that depth. If the shaft shows wear, consider a neighboring size or a seal with the lip in a different position. The selection depends on speed, temperature and the type of lubricant.

If you need an equivalent or a close size, send us the part number 8230 or the shaft, housing and height dimensions. A drawing or a photo of the original seal also works. With that data we look for alternatives in the same series or from other brands we carry. The part number does not have to be exact: we can compare tolerances and design to find an option that performs the function.
