For equipment that needs a reliable barrier between lubricant and the outside environment, the DBH 9278Vit oil seal is a direct-fit option. MR Industrial Accessories supplies this seal to maintenance teams and purchasers across the United States and Latin America. The seal measures 66.67 mm at the shaft, 89.30 mm at the housing, and 10.00 mm in height, and it uses an Mx-R-H lip arrangement. It is commonly found in gearboxes, pumps, motors, and other rotating assemblies where keeping oil in and contaminants out matters.

The Mx-R-H designation tells you this seal has two lips: a main radial lip that holds lubricant against the shaft, and a secondary exclusion lip that blocks dust and dirt from reaching the sealing zone. The outer casing presses firmly into the housing bore, while the elastomer lip maintains contact as the shaft turns. That combination helps protect bearings and keeps the lubricant where it belongs.

You will see the 9278Vit in gear reducers, centrifugal pumps, electric motors, and transmission units. It also shows up in agricultural and mining equipment, where dust and moisture are constant concerns. In those settings, the extra lip acts as a first line of defense, reducing the chance that abrasive particles will work their way into the seal or the bearing cavity.

Before installation, clean the shaft and housing and check for burrs or scratches. Lubricate the lip, then press the seal in squarely so it sits perpendicular to the shaft. When specifying a replacement, confirm the shaft diameter, housing bore, and width, and also consider shaft speed, operating temperature, and how the elastomer will react to the lubricant in use. Exact dimensions are essential for a proper fit.

If you need a cross-reference, send the code 9278Vit or your shaft and housing measurements. MR Industrial Accessories offers a wide range of seals and oil seals in different brands and styles. Our team can suggest an equivalent based on your lubricant, speed, and environmental conditions.
