The DBH 1206 is a radial shaft seal built to the A 065 design, sized for a 56 mm shaft, a 69 mm housing bore and a 17.00 mm height. It keeps lubricant where it belongs and keeps dust, water and particles out of rotating assemblies. You will find this type of seal in pumps, electric motors, gearboxes and other power transmission equipment. MR Industrial Accessories supplies this brand and can help you match the seal to the job.

The code breaks down into two parts: DBH names the seal family, and 1206 is the item designation. The numbers you actually measure are the shaft diameter (d) at 56 mm, the housing diameter (D) at 69 mm and the height (h) at 17.00 mm. A 065 refers to the lip and body geometry set by the manufacturer. Inside the seal there is an elastomeric sealing lip bonded to a metal case, which is what lets you press it squarely into a machined bore and hold it there.

Seals like this one show up on centrifugal pumps, electric motors, gear reducers, gearboxes, transmission shafts and process equipment. In every case the shaft turns while the housing stays fixed. Treat it as a wear part: the lip eventually stiffens or loses material, and that is when you see lubricant weeping out. Catching the leak early is what keeps bearings and gears from taking damage.

Installation starts with clean surfaces. Check the shaft and bore for burrs and scratches, then lubricate the lip before you push the seal in. Seat it perpendicular to the shaft using a driver that presses on the outer edge only. When you pick a replacement, look past the three dimensions: fluid type, operating temperature and shaft speed all affect whether the seal will hold up. If the original part carries a specific design, confirm the new one matches it.

For an equivalent, send the full seal code, a photo and caliper readings if you have them. That is usually enough to locate an option in the same brand or in another line we carry. We can also help when the bore measures slightly off or the space available is narrower than the original.
