The DBH 5120 radial shaft seal is a lip seal that mounts on a rotating shaft to keep lubricant inside the housing and stop dust, water or particles from entering. With a 39.42 mm shaft, 63.55 mm housing and 12.70 mm height, and Lz design, it is a replacement part for equipment where the seal works at moderate speed and with permanent lubrication. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH 5120 radial shaft seal, identified with the designation 5120. Its dimensions are 39.42 mm shaft diameter, 63.55 mm housing diameter and 12.70 mm height. The stated design is Lz, which defines the geometry of the lip and the outer body. It is a seal with a compact cross-section, designed to sit in a machined cavity and rest its lip on the shaft with controlled interference. It is used with rotating shafts that require containment of oil or grease.

Typical applications for a seal of this size appear in gearboxes, pumps, electric motors, drive shafts and process equipment with lubricated bearings. It is also found in machine tools, conveyors and pumping equipment where the lubricated side must be separated from the environment. In all those cases it performs two functions: retaining the lubricant and acting as a barrier against external contaminants, which extends bearing life and reduces downtime due to losses.

To install it, verify that the shaft and housing are clean, free of burrs or marks, and that the shaft surface has the hardness and finish suitable for the lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it directly. When selecting a replacement, compare shaft diameter, housing diameter, height and design type; a difference in lip design changes the behavior under pressure, speed or dirt.
