A radial shaft seal such as the DBH 6818 keeps lubricant where it belongs and keeps dust, water and other particles out of the housing. It works against a rotating shaft, and its size — shaft 28.60 mm, housing 41.25 mm, height 10.50 mm — fits small and mid-size pumps and transmission units. Because the lip wears over time, a hardened or scored lip will start to weep oil and the seal should be swapped out.

The Mx design is a single-lip seal with a metal case and an elastomeric lip, made for lubricated rotating shafts. Its three key measurements are listed on the product page: 28.60 mm at the shaft, 41.25 mm at the housing and 10.50 mm in height. Within the DBH line, 6818 is the code that pins down this particular size, so it is the reference to keep on hand when you place an order.

You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and similar transmission equipment, wherever a shaft turns inside a housing and the oil has to stay separated from the outside. Agricultural machinery, conveyors and process equipment are common applications as well. The job is always the same: hold the lubricant in, keep contaminants out, and help bearings and gears last.

Before installing, confirm the shaft has no burrs or wear at the contact area and that the housing is clean and free of dents. Lubricate the lip, then press the seal in with a flat driver so it does not distort. If the shaft already shows a deep groove, a seal with the lip in a different position may be the better choice. Lubricant type, speed and working temperature all affect the selection.

For an equivalent, send the code 6818 along with the shaft, housing and height measurements and the equipment it fits. That information lets us search the DBH line or other brands we supply. A photo of the old seal and the housing also helps, particularly when the original code is no longer legible.
