The DBH 9579 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 38.10 mm shaft, 50.80 mm housing and 6.35 mm height place it in equipment with medium-section shafts. It is used in pumps, electric motors, gearboxes and rollers, where the seal works alongside the bearing and defines much of the service life of the assembly.

This item is a radial shaft seal from the DBH line, identified with code 9579. Its dimensions are 38.10 mm shaft diameter (d), 50.80 mm housing diameter (D) and 6.35 mm height (h). The Mx design corresponds to the single-lip variant with spring, intended for rotating shafts with grease or oil lubrication. The manufacturer's nomenclature makes it quick to locate when you already have the old number stamped on the seal or in the equipment's parts breakdown.

Typical applications for a seal of this section include electric motors, centrifugal pumps, gearboxes, mixers, conveyors and power transmission equipment. In all cases it performs the same function: keeping lubricant inside the assembly and preventing the entry of contaminants that accelerate wear on the bearing or bushing. It is also found in agricultural machinery, washing equipment and irrigation systems, where the seal must withstand splashes and dust.

To select it correctly, verify that the shaft diameter and the housing diameter match those of the seal, and that the height is compatible with the space available in the housing. Check the condition of the shaft: a scratched or worn surface means the lip will not seal even if the seal is new. During installation, lubricate the lip, seat the seal squarely and tap on the outer ring, never on the lip. If the equipment operates at high temperature or with heavy contamination, ask us about material variants.

To quote 9579, send us the shaft, housing and height dimensions along with a photo of the old seal. With that data we look for the equivalent in DBH or in another line we carry. We can also advise you if the housing has a shoulder or if the shaft shows wear that should be corrected before installing the new seal.
