The DBH 5555 radial oil seal is a lip seal designed to block the passage of oil, grease or water on rotating shafts, and to retain lubrication inside the assembly. It is press-fitted into the housing and works on the shaft with a flexible lip that compensates for small misalignments. It is a wear part: when lubricant loss or contaminant ingress appears, it is replaced. MR Accesorios Industriales carries this brand and advises you so you can choose the correct size.

This item is an oil seal of the DBH brand, part number 5555, with the following dimensions: shaft diameter 45 mm, housing diameter 65 mm and height 12.00 mm. The indicated design is Lz, which corresponds to a single lip with spring and an outer metal body. These dimensions are the ones you need to verify against the shaft and housing before ordering, because a seal with a different height or diameter will not seal correctly.

It is used in gearboxes, pumps, electric motors, transmission equipment and machinery in general where there is a shaft rotating inside a housing and the lubricant must be separated from the environment. It also appears in applications with exposure to dust or water, where the lip prevents contaminants from entering the bearing or gear. It is a small but critical part: if it fails, lubricant loss deteriorates the rest of the assembly.

To install it, clean the housing and the shaft, verify that there are no burrs or marks that could damage the lip, and lubricate the lip with the same grease or oil used in the equipment. Insert the seal perpendicular to the shaft, without hitting the lip, using a tube or shim that presses on the outer ring. If the shaft shows wear in the contact area, consider a nearby size or a seal with an offset lip.

If part number 5555 is not the one you need, send us the dimensions of your seal (shaft diameter, housing diameter and height) or the part number marked on the part. With that data we look for the equivalent in DBH or another brand we carry, or the immediate larger or smaller size. We can also advise you if the Lz design is not suitable for your application.
