The DBH 8772 is a radial lip seal that keeps lubricant in and contaminants out of rotating equipment. It features an A 103-Bidi design with a double lip, and its dimensions are 72 mm shaft, 85.50 mm housing and 8.00/10.50 mm height. The stepped height allows it to fit housings with a shoulder or different mounting depths. MR Industrial Accessories supplies this brand and can help you select the correct seal for your application.

This seal carries the designation 8772 and belongs to the DBH series. Its key measurements are shaft diameter (d) 72 mm, housing diameter (D) 85.50 mm and height (h) 8.00/10.50 mm. The A 103-Bidi code indicates a double-lip configuration, which provides sealing in both directions and extra protection against external particles.

Typical uses include gearboxes, pumps, electric motors, reducers and other power transmission equipment. The seal retains oil or grease on the bearing side while blocking dust, water and chips. It is common in industrial machinery, process equipment and vehicles where shafts rotate at moderate speeds and a reliable barrier is needed.

For proper installation, ensure the shaft and housing are clean and free of burrs or scratches. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in perpendicularly using a tube or socket that contacts the outer diameter. Avoid hitting the sealing lip. Selection should account for rotation speed, working temperature and chemical compatibility between the elastomer and the fluid.

If you need an equivalent, send us part number 8772 or the current dimensions (shaft, housing and height). With that information we can search for alternatives within the same series or from other brands we supply. We can also advise whether a different height or a design with an additional lip would work in your mounting space.
