The DBH 1166 is a radial shaft seal built to design A 378. It seats in a housing bore of 47 mm and has a 6.50 mm height. Its job is to keep lubricant where it belongs and to block dust, water and other particles from reaching bearings and bushings. You will find this type of seal in many rotating assemblies where the shaft turns inside a stationary housing.

The identifying code is 1166, and the seal carries the DBH brand. From the product data, the housing diameter is 47 mm, the height is 6.50 mm, and the design is A 378. Before you order, confirm the shaft diameter at the lip contact point, because that measurement is not fixed by the code alone.

Seals like this show up in gearboxes, pumps, electric motors, transmission shafts and continuous-process equipment. They also appear in conveyors, agricultural machinery and centralized lubrication systems. The goal is always the same: hold oil or grease in and keep contamination out. As the lip ages and loses flexibility, leaks and dirt entry follow, and nearby components wear faster.

Selecting a replacement comes down to three dimensions: shaft diameter, housing bore and height. The shaft surface also matters. Burrs, deep scratches or worn areas will prevent even a correctly sized lip from sealing. When you install the seal, coat the lip with the same lubricant used in the equipment, press it in squarely to the shaft, and avoid hitting the metal case with tools that can distort it. If the housing itself is damaged, you may need to repair it or move to a seal with a wear sleeve.

If code 1166 is not an exact match, or if your shaft diameter differs, an equivalent in the same radial seal category can be identified. The quickest way is to send the original code, a photo of the part, and caliper readings for shaft diameter, housing diameter and height via WhatsApp. With those details, we review alternatives and provide a quote.
