The DBH 8631Pol radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants in rotating equipment. With a 35 mm shaft diameter, 80 mm housing and 9 mm height, it is press-fitted into the housing and works on the rotating shaft. It is a wear part: when oil loss or dust ingress appears, it is replaced. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct seal.

The 8631Pol is a seal with an Lx-H-AH design: spring-loaded sealing lip, metal body and 9.00 mm height. Its dimensions are 35 mm shaft, 80 mm housing and 9.00 mm height. The flexible spring-loaded lip maintains contact on the shaft even with slight eccentricity, and the outer body fits into the housing to secure the part. It is made of elastomer resistant to oils and greases, with metal reinforcement that gives it rigidity when mounting.

These seals appear in gearboxes, pumps, electric motors, reducers, transmission shafts and process equipment. They are also used in agricultural machinery, road equipment and production lines where there are rotating shafts that must be isolated from the environment. In all these cases they perform the same function: retaining lubricant inside the assembly and slowing the advance of water, dust or particles that accelerate wear on bearings and gears.

To select a radial shaft seal, take into account the shaft diameter, housing diameter and height. Also verify the rotation speed, working temperature and type of lubricant, because they determine the lip material. When mounting it, lubricate the lip, insert it perpendicular to the shaft and use a tube or press that presses on the outer edge, never on the lip. If the shaft has burrs or wear, correct it before installing the new seal.

If the 8631Pol is not the size you are looking for, send us the old part number, a photo of the part or the dimensions taken with a caliper. With that data we can locate a nearby size or an equivalent within the same DBH line and the other brands MR supplies. We can also advise you if you need a seal with an additional lip or a different material for a more demanding service.
