A radial shaft seal that keeps lubricant where it belongs and keeps outside contamination out, the DBH 8323 is built to the 48 x 80 x 10 mm size combination and the Lx design. Maintenance teams reach for this size when a gearbox, pump or transmission unit is due for a seal replacement. It sits in our seals and oil seals line.

Reading the reference helps when you are matching a worn part. The designation is 8323, and the three figures that matter on the drawing are the shaft seat at 48 mm (d), the housing bore at 80 mm (D) and the overall height at 10 mm (h). The Lx design tells you what you are holding: one sealing lip, a spring behind it, and no secondary dust lip. That configuration suits a rotating shaft that runs with oil or grease on the inside.

Where does a seal of this footprint usually turn up? Reducers and gearboxes, centrifugal pumps, electric motors and other power transmission assemblies are the common spots. Its job in each of them is the same: hold the lubricant in and keep grit, moisture and stray particles from working their way into the bearing cavity. You will also find it used as a secondary barrier on bearings and bushings where there is not much room along the axis.

Installation decides how long the seal lasts. Look over the shaft first: it should be hard enough and smooth enough, with no burrs, nicks or spiral marks that could score the lip. Coat the lip with the same oil or grease the equipment runs before you slide it on, and seat the seal square to the shaft rather than driving it in with direct hammer blows. If the bore itself is worn, a taller seal or a wear sleeve is worth considering. Lip compound choice comes down to the operating temperature and the fluid being contained.

Matching an equivalent is straightforward if you give us something to work from. Send the code 8323, or simply your measured shaft, housing and height figures, and we can search the DBH range and the other brands we supply. Tell us as well if the original had something unusual, such as a dust guard or a second lip, and we will factor that in. Quotes go out by WhatsApp or email once we have your part number or dimensions.
