A lip seal in the DBH line, the 9771Vit keeps oil and grease where they belong on a turning shaft. It seats in an 86 mm bore, works on a 70 mm shaft and takes up 7.00 mm of axial room, which suits equipment where space along the shaft is tight. Gearboxes, pumps, motors and transmissions all rely on this kind of seal to hold lubricant in and keep dust and water out. MR Industrial Accessories supplies this brand and can help you confirm the right choice.

The code tells you most of what you need. The 9771Vit designation fixes the size and configuration inside the DBH line, and the Mx-R-AH design describes a sealing lip combined with a metal case and a profile built for rotating shaft service. In practical terms: shaft 70 mm, housing 86 mm, width 7.00 mm. A metal reinforcement supports the elastomer so the lip keeps contact through continuous rotation.

Where does it go? Think of centrifugal pumps, electric motors, compressors, gearboxes and transmission rollers. On each of these, the seal separates the lubricated side from the outside, so oil stays in and dust, water and particles stay out. Fans and machine tools with little axial room along the shaft are also common hosts for this size.

Installation rewards care. Inspect the shaft first for burrs, marks or roughness that could score the lip, and confirm the housing depth lets the seal sit flush or slightly recessed. Wipe the lip with the same oil or grease the equipment runs on, then drive the seal in with a tube that presses on the metal case, never on the elastomer. If the shaft itself is worn, a repair sleeve is worth considering.

Need a cross? Send the full part number plus your shaft and housing dimensions. We check the designation and suggest alternatives from the same brand or from other lines we carry, including cases where the axial space differs or the Mx-R-AH design is not the right fit.
