The DBH 9653Pol radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 29.80 mm shaft and a 50 mm housing bore, with a height of 10.00/13.50 mm under design A 103-R. As a wear part, once the lip hardens or shows marks, it can leak oil and should be replaced before bearing damage occurs.

Key dimensions for the DBH 9653Pol are: shaft 29.80 mm, housing 50 mm, and height 10.00/13.50 mm. Design A 103-R indicates a radial shaft seal with a sealing lip and reinforced body, suited for rotating shafts with permanent lubrication. The code 9653Pol defines the size and construction within the DBH line. Before installation, verify that the housing bore is free of burrs or marks left by the previous seal.

Typical applications include gearboxes, centrifugal pumps, electric motors, transmission shafts, and process equipment where oil or grease must be retained. It also appears in agricultural machinery, conveyors, and plant equipment. In all cases, the function is the same: contain lubricant and exclude dirt. For equipment subject to high vibration or temperature, inspect the shaft and housing condition before fitting a new seal.

When selecting a seal, beyond dimensions, consider lip type, material, and shaft peripheral speed. A stainless steel spring or an auxiliary lip may be needed in highly contaminated environments. During installation, lubricate the lip with the same grease or oil used in the equipment, seat the seal squarely, and tap gently on the outer ring—never on the lip. If the shaft is worn, a repair sleeve may be required.
