The DBH 6171 radial shaft seal is a lip seal designed to stop the passage of oil or grease on rotating shafts and prevent the entry of dust and water. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains the seal. It is a wear part: when lubricant leakage appears or dirt enters, it should be replaced. MR Accesorios Industriales carries this brand and helps you identify the correct size for your equipment.

The DBH 6171 is a seal with an Lx design, with a sealing lip and spring. Its dimensions are 57.15 mm shaft diameter, 85.63 mm housing diameter and 15.87 mm height. The Lx design corresponds to a seal with a single lip and metal case, suitable for rotating shafts with lubrication. These are the dimensions you need to verify before ordering: the shaft diameter where the lip runs, the housing bore diameter and the available width.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, rollers, mixers and transmission equipment. Their function is to retain the lubricant inside the assembly and block external contaminants. In environments with dust, water or frequent washing, the seal works under demand and should be checked at every maintenance interval. If the shaft shows wear or scratches in the lip area, the new seal may not seal properly: in that case you need to assess the condition of the shaft or look for a size that runs on a different track.

When selecting a seal, take into account the shaft speed, working temperature and type of lubricant. The lip must remain lubricated; installing it dry accelerates wear. When fitting it, use a press or a tube of suitable diameter that presses on the case, never on the lip, and check that it enters perpendicular to the housing. If the housing has burrs or the shaft has a sharp chamfer, protect the lip with tape or a guide cone so it is not cut during installation.

If you cannot find part number 6171 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we look for the equivalent in DBH or another brand we carry. We can also advise you if the original seal has a different configuration, such as a double lip or reinforced case. The more complete the information about the equipment and the part, the faster we can give you a reliable alternative.
