The DBH 1111 is a radial shaft seal built to keep lubricant where it belongs and to block dust and water from reaching a rotating shaft. It runs on a 25 mm shaft, presses into an 80.2 mm bore and measures 10 mm in height. Treat it as a wear item: once the lip stiffens or lubricant starts weeping past it, replacement is the fix. MR supplies this seal.

Reading the designation helps when you reorder. The 1111 block is the reference tied to this size, while Lx describes the lip geometry and the profile that holds lubricant in place. The three figures that matter are shaft 25 mm, housing 80.2 mm and height 10.00 mm — check them against the old part before you commit to a purchase order.

You will find seals like this in gearboxes, pumps, electric motors, rollers and other transmission equipment. They do two jobs at once: keep oil or grease inside the assembly and keep chips, grit and moisture out. On a machine running in a dirty or wet area, the seal works together with the bearings and any other sealing elements to protect the support points.

Installation decides how long the seal lasts. Inspect the shaft and bore first — no burrs, no scoring, and a surface finish suited to a lip seal. Lubricate the lip, then seat the seal with a tube or press that applies force evenly; never drive it in by hitting the edge. A groove or visible wear track on the shaft will keep a new seal from seating correctly, and in that case a sleeve or a different size is worth considering.

If you are matching an 1111 or chasing an equivalent, send the code, the shaft, bore and height measurements, and a photo of the part. With that we can look for the closest option for your equipment, including situations where the original carries a different designation or the housing itself is damaged.
