The DBH 5423 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 30 mm shaft, 47 mm housing and 5.00 mm height place it in small and medium-sized transmission and rotating equipment. It is a wear part: when the lip hardens or becomes marked, oil leakage begins and it should be replaced.

This item is an oil seal from the DBH line, identified with the code 5423. Its dimensions are 30 mm shaft diameter (d), 47 mm housing diameter (D) and 5.00 mm height (h). The indicated design is Lx, which corresponds to a single-lip seal with metal case and elastomeric sealing lip. It is a radial sealing component: it sits in the cavity of the support or housing and its lip bears with slight interference on the rotating shaft.

It is used in gearboxes, pumps, electric motors, fan shafts, rollers and power transmission equipment in general. Whenever there is a shaft rotating inside a housing with lubricant, the seal performs the dual function of retaining the oil or grease and preventing contaminants from entering. In food, process or light manufacturing plants it appears in equipment where cleanliness and continuity of operation are critical.

To install it, verify that the shaft is within tolerance, free of burrs or marks on the sealing track, and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a flat pusher to avoid twisting it or damaging the spring. If the shaft shows wear, evaluate a repair sleeve before installing the new seal.
