The DBH 8458 radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts, preventing leaks and the entry of dust or water. With dimensions of 24 mm shaft, 40 mm housing and 7 mm height, it is press-fitted into crankcases, covers and gearboxes. It is a wear part that should be replaced when a leak appears or noise is heard in a nearby bearing.

This item is a radial shaft seal from the DBH line, identified with part number 8458. Its dimensions are 24.00 mm shaft diameter, 40.00 mm housing diameter and 7.00 mm height. The Lx design corresponds to a seal with a single sealing lip and metal body, suitable for rotating shafts with permanent lubrication. DBH is a brand that MR carries, so the part arrives with its factory identification and traceability.

Typical applications for a seal of these dimensions include electric motors, centrifugal pumps, speed reducers, gearboxes and power transmission equipment. It is also used on fan, mixer and conveyor shafts where there is contact with oil or grease. In all cases it serves to retain the lubricant inside the assembly and block the entry of external contaminants that accelerate wear on bearings and bushings.

For installation, check that the shaft has no burrs or deep marks and that the housing is clean and free of old sealant residue. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and tap it in with a driver tube that presses on the outer diameter, never on the lip. If the shaft shows wear, consider a neighboring size or a seal with an auxiliary lip. Selection depends on speed, temperature and the type of fluid to be retained.
