The DBH 8801 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and water from entering 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 28.00 mm shaft diameter, 40.00 mm housing diameter and 10.50 mm height, with Lx design. The Lx design defines the lip and metal case configuration, and determines how it seats on the shaft and how it fits into the housing. These values are what you need to compare against the old seal or against the equipment drawing before ordering, because a difference of tenths in height or in outer diameter changes the installation.

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 bushing, and its failure shows up as oil loss, dirt ingress or noise. That is why it is replaced at every scheduled teardown, even if it looks intact at first glance.

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

If the 8801 does not appear on your list or the shaft is worn, we can look for a nearby size or 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 carry, and confirm which option fits without modifying the housing.

MR Accesorios Industriales carries 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 dimension or a sample of the old seal.
