The DBH 5284 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. With dimensions of 70 mm shaft, 90 mm housing and 14 mm height, and Lx design, it is a replacement part for equipment with shafts of that diameter. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

The DBH 5284 is a radial shaft seal with Lx design, with the following dimensions: shaft diameter (d) of 70 mm, housing diameter (D) of 90 mm and height (h) of 14.00 mm. The Lx design corresponds to a single-lip seal with spring, without an external dust lip, intended for applications where the seal works against the lubricant on the inner side and does not require an additional barrier against external contaminants. The designation 5284 identifies this size within the DBH line.

It is used in gearboxes, pumps, electric motors, transmission shafts and rotating equipment in general, where oil or grease leaks must be prevented and bearings protected from the ingress of dirt. It is a wear part: when the lip hardens, cracks or loses elasticity, it starts to lose lubricant and should be replaced before the bearing or shaft suffer damage.

To install it, verify that the shaft is clean, without burrs or deep marks in the contact area, and that the housing has no knocks. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal with a tube or press that bears on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or a seal with the lip in another position.

If you need an equivalent or a close size, send us the full code, the shaft, housing and height dimensions, and a photo of the old seal if you have one. With that data we can look for the exact or closest size within the lines we carry. We can also advise you if the Lx design is not the right one for your application.
