When a rotating shaft passes through a housing and the lubricant inside has to stay there, a radial shaft seal does the work. The DBH 9547 is a lip seal in the Mx design, which pairs a sealing lip with a metal outer body that presses into the housing bore. Its three reference measurements are shaft 35.80 mm, housing 68.00 mm and width 12.00 mm, a combination that maintenance teams run into often when a gearbox, pump or motor starts weeping oil.

Reading the code first saves time. The 9547 identifies the item, and Mx tells you what kind of seal you are holding: a single lip with a spring, with a metal case on the outside. The lip rides against the turning shaft while the case holds the seal firmly in the bore. Those published figures again, in the order most people measure them: shaft 35.80 mm, housing 68.00 mm, width 12.00 mm.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment, and also in road and agricultural machinery. Anywhere a shaft turns inside a housing and oil or grease has to stay on the inside, a seal like this is the boundary between the lubricated side and the outside world. Because it is a wear part, replacing it on schedule is what keeps lubricant where it belongs.

Before fitting a new one, look at the shaft for burrs, scoring or a worn groove, and check that the housing bore is clean and round. Put a little lubricant on the lip, then seat the seal squarely with a proper driver rather than a hammer. How well any seal performs depends on the lubricant in use, the shaft speed and the operating temperature, so it pays to confirm those details. Treat the Mx design as a reference point and verify it against your equipment.

If you are cross-referencing, send the code 9547 or simply the three measurements. Our team can check the DBH line or look at alternatives from the brands we supply. A photo of the old seal plus caliper readings of the shaft and bore go a long way toward avoiding mix-ups. Quotes are handled by WhatsApp or email and answered promptly, and we are glad to help you confirm the right choice.
