The DBH 8801 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and water in equipment with a rotating shaft. With dimensions of 28 mm shaft, 40 mm housing and 10.50 mm height, and Lx design, it is press-fitted into the housing and runs on the shaft. It is a common wear part in motors, pumps and gearboxes, and choosing its geometry correctly extends the life of the bearing and the equipment.

The DBH 8801 is a radial shaft seal with a shaft diameter of 28.00 mm, a housing diameter of 40.00 mm and a height of 10.50 mm, with Lx design. The Lx design defines the configuration of the lip and the metal body, and determines how it seats on the shaft and how it fits into the housing. These values are the ones you have to compare against the old seal or against the equipment drawing before ordering, because a difference of tenths in the height or in the outer diameter changes the mounting.

It is used in rotating equipment where lubricant must be retained and contaminants excluded: gearboxes, centrifugal pumps, electric motors, reducers, transmission shafts and agricultural or process machinery. In all these cases the seal works alongside the bearing or the bushing, and its failure shows up as oil loss, ingress of dirt or noise. That is why it is replaced at every scheduled teardown, even if it looks intact at first glance.

To mount it, clean the housing and the shaft, check that there are no burrs or wear marks on the sealing track, and lubricate the lip with the same grease or oil used in the equipment. The seal is pressed in, perpendicular to the shaft, without hitting the lip or deforming the metal body. If the shaft has a shoulder or keyway, use a protector or tape so as not to cut the lip during sliding. Misalignment is the most common cause of early leaks.

If the shaft is worn, we can look for an equivalent from another brand. For that we need the full part number, the three dimensions (shaft, housing and height), the design type and a photo or sample of the original seal. With that data we review alternatives in the DBH line and in other brands we sell, and we confirm which option fits without modifying the housing.

MR Accesorios Industriales sells the DBH brand as part of its line of seals and oil seals, along with bearings, housings, power transmission and lubricants. If you already have the 8801 part number or the dimensions at hand, send them by WhatsApp and we will send you the quote. We can also help you identify the seal if you only have the shaft measurement or a sample of the old seal.
