The DBH 8171 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 76.20 mm shaft diameter, 101.68 mm housing bore and 12.70 mm height, and an A 183 design, it is press-fitted into the housing and works against the shaft to maintain sealing. It is a common replacement part in industrial equipment operating with continuous rotation and requiring protection against dust, water or particles.

This DBH 8171 oil seal has a shaft diameter of 76.20 mm, a housing bore diameter of 101.68 mm and a height of 12.70 mm. The A 183 design corresponds to a single-lip configuration with spring, intended for rotating shafts where the goal is to contain lubricant and prevent the ingress of external agents. The designation 8171 identifies the exact size within the DBH line, and it is the reference you will use to order the replacement or ask about a nearby size.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where the shaft rotates inside a housing and the passage of oil or grease must be sealed. It also appears in applications exposed to dust or splashes, where the retaining lip performs an exclusion function. It is commonly found in agricultural machinery maintenance, process lines and continuous-motion equipment.

To install it, check that the shaft is clean, free of burrs or wear marks in the contact area, and that the housing has no impacts. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tool that presses on the outer edge, never on the lip. If the shaft has a deep groove, consider a seal with an offset lip or a wear sleeve. Selection depends on the speed, temperature and type of lubricant in the equipment.

If you cannot find the exact size or need an equivalent, send us the part number 8171, the shaft, housing bore and height dimensions, and a photo of the old seal. With that data we can look for an alternative within the DBH line or suggest a compatible nearby size. We can also advise you on the most suitable lip design according to the type of application.
