A compact radial shaft seal, the DBH 9031 closes off the gap where a rotating shaft passes through a housing, keeping lubricant in and dirt or moisture out. Its three key measurements are 10 mm at the shaft, 20 mm at the housing bore and 6.00 mm of height, which makes it a good fit for small, space-tight assemblies. MR Industrial Accessories LLC supplies this reference and quotes it on request.

In code terms, DBH 9031 is an Lx style seal: a metal outer case with one sealing lip backed by a spring. That single-lip layout is what holds oil inside the assembly and pushes contaminants away from the shaft surface. The seal presses into the bore and rides on the shaft, so the running surface needs to be ground smooth and free of nicks for the lip to seat evenly around the circumference.

Because of its small envelope, this size shows up in light and medium-duty drives: fractional and small electric motors, centrifugal pumps, low-power gear reducers, fans, machine tools and auxiliary equipment. It is also a practical answer where radial room is tight and a dependable closure is needed without adding bulk. Treat it as a wear item. Once the lip stiffens, hardens or loses its spring, leakage starts, and swapping the seal early is cheaper than repairing a scored shaft or bore.

Selection comes down to three checks. Confirm the shaft and bore diameters match the published figures, make sure the 6.00 mm height sits flush inside the cavity rather than standing proud, and inspect the shaft for grooves or wear, since a new lip cannot seal against a damaged track. On installation, coat the lip with the same oil used in the equipment, keep the seal square to the shaft and drive it in on the outer case, never on the lip. For high surface speeds or elevated temperatures, ask which lip compound suits the duty.

To get a quote, send the part number along with the shaft, bore and height measurements, plus a photo of the old seal if you have one. Our team can cross it to an equivalent in the same brand or in another line we carry, and will tell you whether the Lx configuration fits your application or whether a different lip type would serve you better. Seals and oil seals are part of our regular range, so you can also ask about other sizes in the same category or the installation tools to seat them without damaging the lip.
