The DBH 9771Vit radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts, seated in an 86 mm bore. Its 7 mm height and Mx-R-AH design make it suitable for equipment with limited axial space. It is used in gearboxes, pumps, electric motors and transmissions where preventing leaks and the entry of contaminants is critical. MR Accesorios Industriales supplies this brand and advises you so you choose the right seal.

This item is a DBH 9771Vit radial shaft seal with the following dimensions: shaft diameter 70 mm, housing diameter 86 mm and height 7.00 mm. The Mx-R-AH design corresponds to a seal with a sealing lip, metal case and a specific profile for applications with a rotating shaft. The 9771Vit designation identifies the size and configuration within the DBH line. It is a precision component that combines a resistant elastomer with a metal reinforcement to maintain sealing under continuous rotation.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission rollers. In all these machines, the seal prevents lubricant leakage and blocks the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used on industrial fan shafts and machine tools where axial space is limited. Its 70 x 86 x 7 mm size matches standard housings in power transmission equipment.

To install this seal correctly, check that the shaft has the proper hardness and roughness, with no burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and use an installation tube that presses on the metal case, never on the elastomer. The 7 mm height requires a housing with just the right depth so the seal sits flush or slightly recessed. If the shaft shows wear, consider a repair sleeve.
