The DBH 8571Pol radial shaft seal is a lip seal designed to block lubricant leakage and prevent contaminants from entering rotating equipment. With a 35 mm shaft, 54 mm housing and 8 mm height, it is press-fitted into the housing and runs on the rotating shaft. It is a wear part that should be replaced when oil leakage or dirt ingress appears. MR Accesorios Industriales supplies it as an official brand.

This item is a DBH 8571Pol radial shaft seal with the following dimensions: shaft diameter 35 mm, housing diameter 54 mm and height 8.00 mm. Its Lx-H-AH design indicates a configuration with a sealing lip, metal case and auxiliary exclusion lip. The main lip retains the lubricant and the secondary lip protects against dust and particles. The 8571Pol designation identifies the geometry and lip material, so it should not be replaced with another seal of the same dimensions but a different design.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where there is continuous rotation and the presence of oil or grease. It also appears in applications with moderate dust exposure, where the auxiliary lip of the Lx-H-AH design provides an additional barrier. It is commonly found in industrial equipment under frequent maintenance, where the seal is replaced together with bearings or bushings during a scheduled repair.

To select it, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The surface condition of the shaft is key: a scratched or worn shaft prevents the lip from sealing properly even if the seal is new. During installation, lubricate the lip with the same grease or service oil, insert it perpendicular to the shaft and avoid striking it. If the housing has burrs, clean it before installing the seal.

If you cannot find the exact size or the Lx-H-AH design is not available, we can look for an equivalent or a nearby size within the DBH line. To do this, send us the 8571Pol code, the dimensions of your current seal and a photo of the housing. With that data we review compatible alternatives and confirm options. We can also advise you if you need to change the lip type or material according to the fluid and working temperature.
