The DBH 8878 radial shaft seal is a lip seal that closes off the passage of oil or grease on rotating shafts and prevents the entry of dust and water. Because of its dimensions of 25 mm shaft, 40 mm housing and 10 mm height, it is used in small and medium-sized gearboxes, pumps and electric motors. MR Accesorios Industriales sells it as part of its seal line, with technical advice to choose the right seal.

This item is a radial shaft seal from the DBH brand, identified with the part number 8878. Its dimensions are 25 mm shaft diameter, 40 mm housing diameter and 10 mm height. The Lx design corresponds to a seal with a single sealing lip and spring, designed to retain lubricant in one direction and keep dirt out. The lip is made of elastomer material and the metal case gives it rigidity for press fitting into the housing.

Typical applications for a seal of these dimensions are input and output shafts of reducers, centrifugal pumps, electric motors, compressors and transmission equipment. It is also found in agricultural machinery, conveyor belts and process equipment where bearings and gears must be protected from contamination. It is always advisable to check that the shaft has no wear or scratches in the contact area, because that shortens the life of the lip.

For installation, clean the housing and the shaft, lubricate the lip with the same grease or oil used in the equipment and fit the seal perpendicular, without striking it from the side. If the shaft shows a burr or a groove, consider a wear sleeve or a nearby size. Selection depends on the speed, temperature and type of lubricant; if you have that data, we can help you confirm whether the 8878 is the right one or whether another lip or material variant is preferable.

If you need an equivalent or a close size, send us the full part number, the shaft, housing and height dimensions, and a photo of the old seal if possible. With that data we search our seal and oil seal line for the option that best fits. We can also advise you on the lip design and material according to the fluid and working temperature.
