With measurements of 17 mm shaft, 40 mm housing and 8.50 mm height, and Lx design, it is a replacement part for equipment with rotary motion. MR Accesorios Industriales sells it as part of its line of seals and oil seals.

This item is a DBH 8484 radial shaft seal, identified by its designation 8484. Its measurements are 17 mm shaft diameter, 40 mm housing diameter and 8.50 mm height. The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts with lubrication. The manufacturer's nomenclature makes it quick to locate in the catalogue and compare 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 impact damage. Lubricate the lip before inserting it and do so with a tool that bears evenly on the metal edge, never on the lip. If the shaft has a deep groove, consider a seal with an offset lip. The selection depends on speed, temperature and the fluid to be retained.
