When lubricant starts escaping around a rotating shaft, the DBH 8408 radial shaft seal is the component that stops it. Its A 224-H lip geometry and metal body suit a 44.20 mm shaft, a 71.45 mm housing bore and a 14.80 mm height, which places it in gearboxes, pumps and motors where bearings need protection and oil or grease has to stay inside the assembly.

This is a DBH lip seal, designation 8408. Shaft diameter 44.20 mm, housing diameter 71.45 mm, height 14.80 mm. The A 224-H design covers both the lip profile and the outer metal case, built for rotating shafts with lubricant on the inner side. Installation is a press fit into the bore, with the lip riding on the shaft.

Sizes like this show up in gearboxes, centrifugal pumps, electric motors, reducers and transmission equipment, as well as agricultural machinery, process lines and pumping systems. The job is twofold: hold the oil or grease in, keep dust, water and particles out of the bearing. A seal is a wear part, so once the lip stiffens or the shaft develops a track, leaking follows.

Matching a replacement starts with three measurements: shaft, bore and height. Confirm they line up with the original before ordering. Inspect the shaft too, since burrs, scoring or a worn track will keep a new lip from sealing. On installation, coat the lip with the same lubricant used in the equipment, set the seal square to the bore and drive it on the outer edge, never on the lip. Remove any burrs from the housing first.

For a quote on part 8408, send the original designation, the three dimensions and a photo of the seal. That is enough for us to cross it to the DBH line or to another brand we carry. If the seal sits next to a bearing, we can help you check both at the same time so a measuring mistake doesn't cost you a second order.
