The DBH 5651 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 63.5 mm shaft diameter, 82.58 mm housing diameter and 12.70 mm height, and Mx design, it is used in gearboxes, pumps and power transmission equipment where lubricant must be retained and dust or water ingress stopped. MR Accesorios Industriales sells it as an official brand.

This item is a DBH 5651 radial shaft seal, identified by its designation 5651. Its dimensions are 63.5 mm shaft, 82.58 mm housing and 12.70 mm height, with Mx design. That combination defines a compact-section seal that runs on a shaft with a nominal diameter close to 2 1/2 inches and is press-fitted into a machined housing. The flexible lip, backed by a spring, maintains contact on the rotating shaft and contains the lubricant.

Typical applications for a seal of these dimensions appear in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. It is also found in agricultural machinery, washing equipment and systems where the shaft rotates continuously and oil, grease or water is present. In all cases, the seal separates two environments: it retains the lubricant inward and blocks contaminants outward.

To select and install the DBH 5651 seal, take into account the condition of the shaft surface: it must be polished, with no burrs or wear marks in the lip contact area. Check that the housing is clean and free of deformation, and lubricate the lip before inserting it. Installation is done with the proper tool, applying uniform pressure on the outer ring, never on the lip. If the shaft shows a groove or wear, consider a nearby size or a repair sleeve.

If you need an equivalent or a size close to the 5651, send us the full part number and the shaft, housing and height dimensions.

It is also advisable to indicate the type of lubricant, the operating temperature and the shaft speed, because they influence the choice of lip and spring material.
