The DBH 9342 radial shaft seal is a lip seal mounted in cylindrical housings to retain lubricant and exclude contaminants on rotating shafts. Its designation 9342 corresponds to a seal with a 52 mm shaft diameter, 70 mm outer diameter and 8.00 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment where preventing leaks and the ingress of dust or water is critical. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal.

This item is a radial shaft seal from the DBH brand, identified by part number 9342. According to its attributes, it is designed for a shaft with a diameter (d) of 52 mm, a housing with a diameter (D) of 70 mm and a total height (h) of 8.00 mm. The Lx design indicates a specific construction within the DBH seal line, which defines the shape of the lip and the metal body. It is a sealing component that works by direct contact on the shaft, with a flexible lip that rests on the machined surface and an outer body that is press-fitted into the housing.

Typical applications for a seal of these dimensions include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all these cases, the seal serves two functions: retaining the lubricating oil or grease inside the assembly and preventing abrasive particles, water or vapors from entering that accelerate wear on bearings and gears. It is also found in machine tools, industrial washing equipment and conveyor systems, where the working environment is demanding.

To install a radial shaft seal correctly, verify that the shaft and housing diameters match the indicated values: 52 mm and 70 mm respectively. The 8.00 mm height must fit into the cavity without forcing. Before installing, lubricate the lip with the same oil or grease used in the equipment, check that the shaft has no burrs or marks and that the housing is clean and free of dents. The seal is driven in with a suitable installation tube, applying even pressure on the outer ring, never on the lip. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
