The DBH 1263 seal is a radial lip seal, designed to close the passage of oil or grease at the point where a rotating shaft passes through a housing. Its design A 414 combines a sealing lip with a metal body that fits by pressure into the cavity. It is used in gearboxes, pumps, electric motors and reducers, where it prevents leaks and the entry of dust or water. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct size.

This item is a DBH 1263 radial shaft seal, with the following dimensions: shaft diameter 31 mm, housing diameter 43 mm and height 8.00/14.00 mm. Design A 414 corresponds to a seal with a sealing lip and sheet metal body, suitable for press mounting in the housing. The double height (8 and 14 mm) indicates that the sealing section is 8 mm and the assembly with the outer flange reaches 14 mm, which allows covering cavities with different shoulders. These dimensions are those listed in the manufacturer's data sheet and are the ones you must verify before ordering.

Typical applications for a seal of this size include transmission shafts, centrifugal pumps, electric motors, gearboxes and process equipment. In all cases, the seal keeps the lubricant inside the assembly and blocks the ingress of external contaminants. It is a wear part: over time, the lip hardens or wears and leakage appears. That is why it should be checked at every preventive maintenance and replaced when an incipient leak or axial play in the shaft is detected.

To mount this seal, verify that the shaft has the indicated size, free of burrs or marks, and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease as the equipment before inserting it, and do so with a support tube that rests on the metal edge, never on the lip. If the shaft shows wear, evaluate a nearby size or a seal with an auxiliary lip. Selection depends on speed, temperature and the type of lubricant; if you do not have that data, consult us and we will guide you.
