The DBH 8772 seal is a radial lip seal, designed to stop lubricant from escaping and keep contaminants out of rotating equipment. Its A 103-Bidi design and its dimensions of 72 mm shaft, 85.50 mm housing and 8.00/10.50 mm height make it suitable for applications requiring a double lip and a variable mounting height. MR Accesorios Industriales sells this official brand and advises you so you choose the correct seal for your equipment.

This item is a DBH radial shaft seal, identified by the designation 8772. Its main attributes are: shaft diameter (d) of 72 mm, housing diameter (D) of 85.50 mm and height (h) of 8.00/10.50 mm. The A 103-Bidi design indicates a double-lip configuration, which improves sealing in both directions and provides greater protection against external particles. The stepped height allows the seal to adapt to housings with a shoulder or to different mounting depths.

Typical applications of this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment in general. It is used to retain oil or grease on the bearing side and, at the same time, prevent the entry of dust, water or chips. It is commonly found in industrial machinery, process equipment and vehicles where the shaft rotates at moderate speeds and conditions demand a reliable barrier.

To install this seal correctly, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and press perpendicularly using a tube or socket that bears on the outer diameter. Avoid striking the sealing lip. Selection must consider rotation speed, working temperature and the chemical compatibility of the elastomer with the fluid to be retained.

If you need an equivalent seal or a nearby size, the most practical approach is to send us part number 8772 or the current dimensions (shaft diameter, housing and height). With that data we can search for alternatives within the same series or from other brands we sell. We can also advise you if the mounting space allows a different height or if a design with an additional lip is a better fit.
