The DBH 5400 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft rotates inside a housing. Its function is to retain the lubricant and stop the ingress of dust, water or particles, protecting bearings, bushings and gears. It is press-fitted into the housing and runs against the shaft, with a flexible lip that compensates for small misalignments and vibration inherent to rotation.

This item is a DBH oil seal with the designation 5400. Its dimensions are 19 mm shaft, 41.24 mm housing and 6.35 mm height, with Lx design. That combination defines a seal with a compact cross-section, intended for small-diameter housings and low to medium speed shafts. The Lx design corresponds to a single sealing lip with a metal case, suitable for grease or oil lubrication and for continuous service in light and medium industrial equipment.

Typical applications for a seal of these dimensions appear in small gearboxes, electric motors, centrifugal pumps, fans, screw compressors and transmission equipment. It is also used in machine tools, conveyors and process equipment where lubricant must be contained on a 19 mm shaft. In all cases it is advisable to verify that the housing and the shaft are in good condition before replacing the seal.

To install a radial shaft seal, clean the housing and the shaft, check that there are no burrs or wear marks and lubricate the lip before inserting it. The seal must enter perpendicular, without blows that deform the metal case. When selecting, take into account the shaft speed, the working temperature and the type of lubricant. If the shaft shows wear, evaluate a neighboring size or a seal with an auxiliary lip to restore sealing.
