The DBH 5136 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants on rotating shafts. With dimensions of 12 mm shaft diameter, 30 mm housing bore and 8 mm height, and an Lx design, it is press fitted into the housing and works on the shaft with a flexible lip. It is a key part in pumps, electric motors, gearboxes and power transmission equipment, where reliable sealing extends the service life of bearings and gears.

This item is a radial shaft seal from the DBH brand, identified with the code 5136. Its standard dimensions are 12 mm shaft diameter (d), 30 mm housing bore (D) and 8 mm height (h). The Lx design corresponds to a configuration with a sealing lip and spring, suitable for applications where the shaft rotates and oil or grease must be contained. The lip elastomer and the metal body guarantee resistance to wear and to service temperature.

Typical applications for this oil seal include centrifugal pumps, low-power electric motors, gear reducers, transmission shafts and machining equipment. In all cases, its function is to retain lubricant inside the assembly and block dust, water or particles that could damage the bearings. Due to its compact size, it is common in small equipment or in spaces where sealing must be precise and long lasting.

To install the seal correctly, verify that the shaft has the appropriate hardness and roughness, and that the housing is clean and free of burrs. Installation is done with a tool applying uniform pressure on the outer ring, never on the lip. Before mounting, lubricate the lip with the same oil or grease used in the equipment. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
