The DBH 5205Pol 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. It is press-fitted into the housing and its flexible lip rests on the shaft, retaining lubricant and slowing the ingress of dust, water or particles. It is a wear part: when leakage appears, it is replaced by size. MR Accesorios Industriales carries this brand and helps you identify the correct size.

This item is a seal of design A 003 with the following dimensions: shaft diameter 39.42 mm, housing diameter 80.26 mm and height 14.25 mm. Those three dimensions define the seat: the lip works on the shaft, the outer contour rests in the housing and the height determines how far it enters the cavity. Before ordering, it is advisable to compare all three against the old seal or against the equipment drawing, because even a minimal difference prevents correct installation.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing with lubricant. It also appears in applications exposed to dust or water, where the seal serves a dual function: it retains oil inward and blocks the ingress of contaminants from outside. In those cases, the condition of the lip and the shaft defines the service life of the seal.

To select correctly, check the shaft and housing diameters with a caliper, verify that the shaft has no burrs or wear on the support track and confirm that the cavity is clean and free of dents. During installation, lubricate the lip, align the seal without tilting it and tap evenly on the outer contour, never on the lip. If the shaft shows a deep mark, the new seal may leak there even if the size is correct.
