The DBH 6901 radial shaft seal is a lip seal designed to block the passage of oil or grease at the point where a shaft passes through a housing. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in rotating industrial equipment, and its size and design suit installations that require reliable, low-maintenance sealing.

This item is identified by the designation 6901 and corresponds to a DBH brand radial shaft seal. Its dimensions are shaft 72 mm, housing 95 mm and height 16.00 mm, with an A 111 design. Those three dimensions define the fit: the inner diameter seats on the shaft, the outer diameter seats in the bore and the height determines how far it protrudes or is recessed into the housing. Before replacing, it is advisable to verify that all three match the original part.

Typical applications for a seal of this size appear in gearboxes, pumps, electric motors, rollers and power transmission equipment where a shaft rotates inside a lubricated support. It is also used in machine tools and process equipment that work with oil or grease and need to contain the lubricant. In all cases, the seal protects the nearby bearings or bushings and extends the service life of the assembly.

To install a radial shaft seal, the housing must be clean, free of burrs and marks, and the shaft free of splines or edges that could cut the lip. It is advisable to lubricate the lip with the same grease or oil used in the equipment before inserting it, and to use a tube or press that bears on the outer diameter, never on the lip. Selection depends on shaft speed, operating temperature and the type of fluid; if these data are not clear, ask us and we will help you define the right design.

If you need an equivalent, the most practical approach is to send us the part number 6901 along with the shaft, housing and height dimensions. With that data we can look for an alternative within the same radial shaft seal category or suggest a design that better suits your application. We can also advise you if the housing has a shoulder or if the shaft shows wear.
