A lip seal in the Lx configuration, the DBH 8320 keeps lubricant inside the housing and keeps dust, chips and moisture out. It fits a 14 mm shaft, a 28 mm bore and a 7.00 mm width, so it suits tight assemblies where a dependable seal is required. Because it wears in service, it is normally renewed as part of scheduled maintenance.

Reading the size callout is straightforward: shaft 14 mm, housing 28 mm, width 7.00 mm. The Lx layout pairs a primary sealing lip with a secondary exclusion lip, so the seal works on two fronts at once — holding oil or grease against the bearing and blocking outside particles before they reach the main lip. The outer shell is elastomeric and the lip is normally backed by a steel spring that keeps pressure against the shaft.

Typical installations include small electric motors, gear reducers, pumps, compressors, machine tools and power transmission assemblies, as well as automotive and agricultural equipment where lubricant has to stay in the bearing cavity. Fans, mixers and conveyor shafts are common spots. The compact envelope helps where radial room is limited, and the exclusion lip is an advantage in dusty, chipped or wet surroundings.

Selection comes down to matching the three dimensions to the actual shaft and bore, then confirming the design type. The shaft should be ground, smooth and free of burrs, with sufficient hardness to resist wear. When pressing the seal in, coat the lip with the same oil or grease used in service, keep the seal square to the bore and avoid impacts on the lip. If the shaft already shows a wear groove, a repair sleeve or a shifted mounting position may be the better route.

If you need a replacement or an equivalent for the DBH 8320, send the complete code or the dimensions 14x28x7 mm along with the design type. It also helps to know the measured shaft and bore diameters, the lubricant used and the operating speed and temperature, since the bore may allow a different height within an acceptable range. With those details we can propose options from other brands or from our own line.
