A radial shaft seal such as the DBH 9039 keeps lubricant where it belongs and keeps contaminants out of the bearing area. This Lx seal has a single lip and a metal case with elastomer, sized for a 10 mm shaft, a 22 mm housing bore and a 7.00 mm width. It is press-fitted into covers, small gearboxes and electric motors, and it is treated as a wear part: once the lip hardens or oil starts to weep, it gets swapped and the assembly runs clean again.

Reading the size is straightforward: d = 10 mm is the shaft the lip rides on, D = 22 mm is the bore that holds the case, and h = 7.00 mm is the width available in the housing. The lip contacts the rotating shaft while the case stays fixed in the bore, and that pairing is what makes the seal work. Inspect the shaft before pressing a new one in; nicks, burrs or a worn groove under the lip will shorten the life of any seal.

Typical applications include small electric motors, gear reducers, centrifugal pumps, compressors, conveyor drives and general power transmission equipment, as well as machine tools, agitators and industrial fans. In each case the job is the same: hold oil or grease inside the assembly and block particles from working their way in from outside. Compared with the cost of a failure caused by lost lubrication, the seal itself is a minor expense.

When choosing a replacement, confirm all three measurements rather than the part number alone. The Lx configuration is a single-lip design intended for moderate speeds and low pressures. If the surrounding conditions involve heavy dirt or elevated heat, it is worth reviewing a lip with a dust guard or a different elastomer compound. The shaft surface should be ground and lightly lubricated during installation so the lip is not cut or rolled on the way in.

If the original is not available, our team can review equivalents. Send the code stamped on the old seal along with the shaft and housing dimensions, and a photo if you have one; the machine or equipment code also helps narrow the options within the DBH line and the other brands we supply.
