MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH 8484 radial shaft seal, identified by its designation 8484. Its dimensions are 17 mm shaft diameter, 40 mm housing diameter and 8.50 mm height. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The manufacturer's nomenclature makes it easy to locate in the catalog and compare it with other alternatives in the same series.

It is used in gearboxes, pumps, electric motors, rollers and power transmission equipment where a shaft rotates inside a housing and oil or grease must be contained. It also appears in machine tools, mixers and conveyors. It is a wear part: when the lip hardens or becomes marked, it starts to leak and should be replaced before it damages the bearing or the shaft.

To install it, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. Lubricate the lip before inserting it and do so with a tool that presses evenly on the metal edge, never on the lip. If the shaft has a deep groove, consider a neighboring size or a seal with an offset lip. Selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a close size, send us the part number 8484 along with the shaft and housing dimensions, a photo of the old part if you have one, and the equipment where it is mounted. With that data we search the DBH line and the available alternatives. We can also check whether a seal with a different height or a different design is better for your application.
