The DBH 9781 radial shaft seal is a single-lip seal that is mounted in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. With dimensions of 12 mm shaft, 24 mm housing and 5 mm height, and Lx design, it is used in pumps, electric motors, gear reducer boxes and power transmission equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line.

The DBH 9781 is a radial lip seal with the following dimensions: shaft diameter 12 mm, housing diameter 24 mm and height 5.00 mm. Its Lx design indicates a single-lip configuration with a spring, suitable for rotating shafts. The elastomeric lip presses against the shaft and the spring maintains contact pressure to compensate for wear. The outer metal case ensures a firm fit in the housing. It is a common replacement part in equipment where oil or grease must be contained and leaks prevented.

This seal is used in applications where axial space is limited and the shaft rotates at moderate speeds. It appears in small centrifugal pumps, low-power electric motors, gear reducers, compressors, fans and machine tools. It is also found in power transmission equipment and in linear motion mechanisms where the shaft passage needs to be sealed. Its compact size makes it common in laboratory equipment, instrumentation and precision machinery.

To select the seal correctly, verify that the shaft diameter and housing diameter match the indicated values. The 5.00 mm height must fit into the cavity without forcing. Before mounting, lubricate the lip with the same oil or grease used in the equipment and make sure the shaft has no burrs or marks that could damage the seal. The Lx design tolerates slight misalignment, but the shaft should be aligned with the housing. If the equipment operates in very dirty conditions, consider adding a protective seal or an additional lip.
