The DBH 9378 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 42 mm shaft diameter, 80 mm housing diameter and 8.00 mm height place it in medium-sized transmission and rotating equipment. MR Accesorios Industriales carries it as part of its seals and oil seals line.
This item is a DBH brand radial shaft seal, identified by part number 9378. Its published attributes are: shaft diameter (d) 42 mm, housing diameter (D) 80 mm, height (h) 8.00 mm and Lx design. The Lx design corresponds to a seal with a sealing lip and an outer metal body, intended for housings that require a firm fit and an effective barrier against leaks. The 9378 designation places it within the range of DBH seals that MR carries.
Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, rollers and belt or chain drive equipment. In all cases it serves to confine the oil or grease in the bearing and prevent contaminants from entering from outside. It is a wear part that should be checked when lubricant leaks or abnormal noises appear in the seal area.
To correctly select and install a radial shaft seal, verify that the shaft diameter, housing diameter and height match the values of the original part. The shaft surface must be clean, free of burrs and deep marks, and the lip must be lubricated before insertion. Installation is done with the proper tool, applying uniform pressure on the outer ring, never on the lip. If the housing shows wear, consider a repair or the use of a seal with a wear sleeve.
If you need a nearby size or an equivalent from another brand, you can send us part number 9378 along with the shaft, housing and height dimensions shown on your equipment. With that data we check alternatives within the DBH line or other brands we carry. We can also advise you if the Lx design is not suitable for your application and a different lip type or material is needed.
