When a rotating shaft starts weeping oil, the first thing to check is usually the seal. The DBH 1216 is a radial shaft seal built for a 56 mm shaft, a 72.30 mm housing bore and an 8.00 mm height, and it carries the A 322 design. MR supplies this brand, so you can order it by its specific part number instead of matching dimensions by eye.

Reading the code helps you order correctly. The 1216 designation ties the seal to this size combination, while A 322 describes how the seal itself is built: an elastomeric lip backed by a spring, with the outer diameter seating in the housing. In service, the lip runs against the shaft and holds lubricant in, while the same lip keeps dust, water and particles out of the assembly.

You will find seals like this one in gearboxes, pumps, electric motors, transmission shafts and other process equipment. Anywhere a shaft turns and oil or grease has to stay put, a seal of this type is doing the work. In plants and workshops, keeping that barrier intact is what protects bearings and keeps lubrication where it belongs.

Installation is where most premature failures start. The shaft should be clean, free of burrs and with the correct surface finish before the seal goes in. Lubricate the lip, then press on the outer diameter with a proper driver rather than on the lip itself. Depending on how the housing is machined, the 8.00 mm height sits flush or slightly recessed. If the shaft already shows a groove or wear, a repair sleeve is worth considering.

If you need a different size or an equivalent, send the complete seal part number along with the shaft, housing and height dimensions, plus a photo of the part. With that information we can look for an alternative in the same series or from another brand we carry, and we can tell you whether the A 322 design is the right choice for your operating conditions.
