The DBH 6120Pol is a radial shaft seal that keeps lubricant in and contaminants out. It fits a 22 mm shaft, a 40 mm housing bore and a 7 mm width, and its Mx-R designation describes how the seal is built within the DBH line. This compact size appears often in power transmission components and small pumps, and MR Industrial Accessories LLC supplies it as part of its seals and oil seals range.

As a single-lip seal, the 6120Pol runs against the rotating shaft and seats in the housing. The three dimensions to work with are shaft 22 mm, housing 40 mm and width 7 mm. Because the 7 mm width is relatively narrow, it suits shallow bores, covers and end plates where there is not much axial room. The lip is the friction surface, so it is the part that wears over time.

Typical installations include gearboxes, centrifugal pumps, electric motors, rollers and other power transmission equipment where oil or grease has to stay separated from the surrounding environment. The same size also shows up in machine tools, agitators and process machinery. When the lip begins to fail, the usual clue is a lubricant stain near the shaft or contamination working its way toward the bearing.

During installation, confirm the shaft is clean and free of burrs or machining marks, then apply lubricant to the lip before sliding the seal into place. Keep the seal square to the shaft and press evenly on the outer diameter with a tube or spacer rather than striking it at an angle. If the shaft already shows a groove or wear, an offset-lip version may be the better choice, since the lip needs a sound shaft surface to seal correctly.

If you are looking for an equivalent, send part number 6120Pol along with the equipment brand and, when available, the shaft, housing and width measurements. With those details we can check the DBH line and the other brands we carry. We can also point you to a variant with a spring or a double lip if your application calls for it.
