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 stop the entry of dust, water or particles that wear down bearings and bushings. It is press-fitted into the housing and runs supported on the shaft, which is why the precision of both dimensions is what defines its performance.

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

The typical applications of 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 correctly, 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 mounting, the seal is installed 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.

To quote the code 8029, send us the shaft, housing and height dimensions along with a photo of the old part. With that data we will indicate the equivalent in the same brand or in another with similar characteristics, and we will confirm whether the A 248 design corresponds to what you have mounted. We can also verify against the manufacturer's data sheet if there are any doubts.
