The DBH 8971 radial shaft seal is a lip seal mounted in the housing and closing against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions are 70 mm shaft, 110 mm housing and 8.00 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and transmission equipment where bearings must be protected and lubrication kept inside the assembly.

This item is a radial shaft seal from the DBH line, identified by part number 8971. It works on a shaft of 70 mm diameter, fits a housing of 110 mm and has a height of 8.00 mm. The Lx design corresponds to a single-lip seal with a spring, intended for rotating shafts with internal lubrication. The elastomeric lip bears against the shaft and the outer case maintains the fit in the housing. It is a wear part: when the lip hardens or becomes marked, it starts to lose oil.

Typical applications for a seal of these dimensions appear in gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. It is also used in machine tools, mixers and conveyors where a shaft rotates inside an oil-filled housing. In all these cases the function is the same: to prevent lubricant from escaping and external contaminants from reaching the bearing or gear.

To install it, verify that the shaft is within tolerance and free of burrs, and that the housing has no dents or rust in the seating area. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, using a tube or spacer that bears on the outer edge, never on the lip. If the shaft is worn, consider a seal with an offset lip. The selection depends on the type of lubricant, the temperature and the rotation speed.

If you need an equivalent or a different size, send us part number 8971 along with the shaft, housing and height dimensions, and the type of equipment where it is mounted. A photo of the old seal or the seat also helps. With that data we look for the replacement within the DBH line and quote you. If the Lx design is not suitable for your application, we will evaluate it with you.
