The DBH 8383 oil seal is a radial seal with 50 mm shaft diameter, 85 mm housing bore and 10 mm height, with Lx design. It is used to retain lubricant and exclude contaminants in rotating equipment such as pumps, electric motors, gearboxes and bearings. Its elastomer lip runs on the rotating shaft and its metal case fits into the housing. It is a wear part that should be replaced when oil loss or dust ingress appears.

The DBH 8383 is a radial shaft seal with the following dimensions: shaft diameter 50 mm, housing bore diameter 85 mm and height 10 mm. The Lx design corresponds to a seal with a sealing lip and spring, intended for rotating shafts with lubrication. The 8383 designation identifies this size within the DBH line. Made with elastomer and a steel case, it is designed to withstand continuous rubbing against the shaft and maintain sealing under normal working conditions.

Typical applications of this seal include centrifugal pumps, electric motors, gear reducers, gearboxes, conveyor rollers and power transmission equipment. In all cases, its function is twofold: to prevent lubricant from escaping and to prevent dust, water or particles from entering the bearing or mechanism. It is a critical part in the reliability of rotating equipment, so it should be checked at every preventive maintenance interval.

To install the seal correctly, verify that the shaft diameter is within the recommended tolerance and that the contact surface is clean and free of burrs. The housing must be machined to the nominal 85 mm diameter and free of damage. Lubricate the lip before installing and use an installation tool that bears on the case, never on the lip. If the shaft shows wear, consider an oversized repair size or a seal with an additional lip.

If you need an equivalent seal or a nearby size, the most practical thing is to send us the full code engraved on the part or the dimensions measured with a caliper: shaft diameter, housing bore diameter and height. With that data we can look for alternatives in other brands or series that perform the same function. We can also advise you if the Lx design is not the right one for your application.
