The DBH 8029 radial shaft seal is a lip seal that closes off the passage of oil and grease at the point where a shaft rotates inside a housing. Its function is to retain the lubricant on the inner side and to stop the ingress of dust, water or particles that wear down bearings and bushings. It is press-fitted into the housing and works supported on the shaft, which is why the precision of the two measurements is what defines its performance.

This item is identified with part number 8029 and corresponds to a seal with A 248 design. Its measurements are a shaft of 42.86 mm, a housing of 59.13 mm and a height of 12.70 mm. Those three dimensions are what you need to compare before replacing a part: the shaft diameter defines the fit of the lip, the housing diameter the installation interference and the height the position within the cavity. If any of them does not match, the seal will not seal properly.

Typical applications for a seal of this size appear in gearboxes, pumps, electric motors, transmission shafts and process equipment where there is continuous rotation with lubrication. It is also used in agricultural machinery, materials handling equipment and production lines that work with dust or moisture. In all those cases it performs the same function: separating the external environment from the lubricant that protects the bearings.

To select well, check the condition of the shaft surface: a new lip will not seal on a scratched or worn track. Also verify the housing, the type of lubricant and the working temperature. During installation, the seal is fitted with a press or with a tube supporting the outer edge, never by striking the lip, and it is advisable to lubricate the edge before sliding it onto the shaft so as not to damage it.
