The DBH 8441 is a radial shaft seal, the type of lip seal that presses into a housing and rides against a turning shaft. It keeps oil or grease where it belongs and keeps dust, water and debris out. The published size is 68 mm at the shaft, 90 mm at the housing bore and 13 mm in height, with the Mx lip and metal case configuration. MR Industrial Accessories includes it in its seals and oil seal line.

Reading the code and the size together is the quickest way to confirm a match. The 8441 identifies the DBH item; the three figures describe the bore it presses into, the shaft it contacts and how wide it sits. The Mx designation tells you how the lip and the metal body are built, which matters when you compare it against what came out of the machine.

You will find seals in this size range on gearboxes, centrifugal pumps, electric motors, rollers and other transmission equipment. In every case the job is the same: hold the lubricant in and hold contamination out. Where chips, grit or washdown water are present, a seal that seats correctly is what keeps the bearings and gearing behind it running.

Before installation, confirm the shaft diameter, housing bore and height against the original part. Lubricate the lip, and inspect the shaft for burrs, scoring or a worn contact band. If you are replacing a failed seal, look at the shaft surface and the housing bore as well, since a rough or damaged surface will shorten the life of the replacement.

From that we can search the radial seal category for a direct size or for a workable combination of diameters and height. If a different construction needs to be considered, we can tell you what to check before you commit.
