The DBH 5757 radial shaft seal is a lip seal that closes off the passage of lubricant and blocks the ingress of dust and water on rotating shafts. With a 19 mm shaft diameter, 31.73 mm housing diameter and 9.52 mm height, and Mz design, it is press-fitted into the housing and runs on the rotating shaft. It is a wear part: when oil loss appears or dirt gets in, it is replaced. MR Accesorios Industriales sells it as an official brand.

This item is a seal from the DBH line, identified by code 5757. Its dimensions are 19 mm shaft diameter (d), 31.73 mm housing diameter (D) and 9.52 mm height (h). The Mz design defines the geometry of the lip and the metal body, intended to retain lubricant and exclude contaminants on a shaft that rotates inside a fixed housing. The flexible lip bears on the shaft and the outer body is seated under pressure in the bore.

It is used in gearboxes, pumps, electric motors, compressors, spindles and transmission equipment where a shaft rotates and the oil must be separated from the environment. It also appears in agricultural machinery, process lines and factory equipment. In all those cases it performs the same function: keeping the lubricant inside and dust, water or particles outside, protecting bearings and gears.

To select it, check that the shaft diameter, the housing diameter and the height match those of the original seal, and that the Mz design is suitable for your application. Check the condition of the shaft: a scratched or worn surface means the lip will not seal properly. When mounting, lubricate the lip, seat the seal squarely and press it in with a tube or press that pushes on the outer body, never on the lip.

If you cannot find code 5757 or you need a neighboring size, send us the dimensions of the old seal — shaft diameter, housing diameter and height — or a photo of the part. With that data we look for the equivalent in DBH or another brand in the same category. We can also check the Mz design against the manufacturer's data sheet to confirm that the lip and body geometry is the right one for your equipment.
