The DBH 5651 is a radial shaft seal that keeps oil or grease on one side of a rotating shaft and keeps dust and water on the other. Its Mx design and its measurements — shaft 63.5 mm, housing 82.58 mm, height 12.70 mm — place it in gearboxes, pumps and power transmission equipment. MR Industrial Accessories supplies this seal as a brand item.

The designation 5651 identifies the seal within the DBH line. Reading the three figures in order tells you where it fits: 63.5 mm is the nominal shaft it runs on, close to 2 1/2 inches; 82.58 mm is the bore it is pressed into; 12.70 mm is the overall height. The Mx design covers a compact cross-section, and a spring-loaded lip rides against the rotating shaft to hold the lubricant in place.

You will find seals of this size in gearboxes, reducers, centrifugal pumps, electric motors and other power transmission assemblies. They also appear in agricultural machinery, washing equipment and any setup where the shaft turns continuously and oil, grease or water is nearby. In every case the seal does one job: it separates the two environments.

Before fitting the DBH 5651, look at the shaft surface. It should be polished, with no burrs or wear marks where the lip contacts it. The housing must be clean and free of deformation. Lubricate the lip before insertion, drive the seal in with the correct tool, and apply even pressure on the outer ring only — never on the lip. If the shaft already shows a groove, a repair sleeve is the usual next step.

When you need a replacement or an equivalent for the 5651, send the complete part number along with the shaft, housing and height measurements. From there we can check the DBH line and other brands we carry. It also helps to note the lubricant type, the operating temperature and the shaft speed, since those details affect which lip and spring material will work.
