The DBH 5647 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 52.40 mm shaft diameter, 73.02 mm housing bore and 9.52 mm height make it suitable for equipment where axial space is limited. It is used in gearboxes, pumps, electric motors and transmissions operating at moderate peripheral speeds. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a seal of Mz design, identified with code 5647 from the DBH brand. Its standardized dimensions are: shaft diameter 52.40 mm, housing bore 73.02 mm and height 9.52 mm. The Mz design corresponds to a seal with a single sealing lip and metal case, intended for press-fit mounting in a cylindrical housing. The lip elastomer is formulated to resist mineral oils and greases, and the internal spring maintains contact pressure on the shaft. It is a standard replacement part in rotating equipment.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, transmission shafts and machinery rollers. In all cases, its function is twofold: to prevent lubricant from leaking outward and to block the entry of dust, water or particles that accelerate wear of bearings and gears. Because of its reduced height, it fits housings where there is no room for wider seals. It is commonly found in continuous-process equipment, where sealing reliability is critical.

To correctly select a seal, verify that the shaft and housing dimensions match those of the equipment. The shaft surface must be ground and free of splines or burrs that could damage the lip. Before mounting, lubricate the lip with the same oil used in the system and verify that the spring is correctly positioned. The seal is installed with a press or rubber mallet, applying uniform force on the outer diameter. Avoid striking the lip and make sure the housing is clean and free of burrs.
