The DBH 5756 radial shaft seal is a lip seal mounted in the housing and sealing against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 19 mm shaft, 31.75 mm housing and 9.52 mm height place it in small and medium-sized equipment, where axial space is limited. It is used in pumps, electric motors, gearboxes and transmissions that need a reliable, low-maintenance barrier.

This item is a DBH 5756 radial shaft seal, identified by its designation 5756. It works on a shaft of 19 mm diameter, fits into a housing of 31.75 mm and has a height of 9.52 mm. The Mz design defines the geometry of the lip and the metal body, intended to fit in the cavity without deforming during installation. It is a direct replacement part: if the old seal shows the same designation, it replaces without modifications.

Typical applications appear in equipment with 19 mm shafts: small centrifugal pumps, electric motors, gearboxes, compressors, fans and machine tools. It is also found in belt or chain transmissions where the oil must be separated from the environment. In all cases it performs two functions: preventing lubricant leaks to the outside and stopping the advance of contaminants toward the bearings or bushings.

To select the seal correctly, verify that the shaft diameter, the housing diameter and the height match the values on the product page. The condition of the shaft matters: a scratched or worn surface means the lip will not seal. During installation, lubricate the lip, insert it perpendicular to the shaft and use a tube or shim that rests on the metal body, never on the lip. If the equipment works at high speed or temperature, consult us about material variants.

If you need a nearby size or an equivalent from another brand, send us the full code, the shaft, housing and height dimensions, and a photo of the original seal. With that data we review alternatives within the DBH line or from other brands we carry. We can also advise you if the Mz design is not the right one for your application and another lip profile should be evaluated.
