The DBH 6808 is a radial shaft seal with a single lip, sized for a 17 mm shaft and a 28 mm bore. Its height is given as 7.00/12.80 mm, and it uses the A 117-Hel profile. This seal keeps lubricant inside and blocks dust, water and particles from reaching bearings and gears in rotating equipment. It fits pumps, electric motors, gearboxes and transmissions where axial room is tight but a dependable barrier is still required.

The code 6808 identifies this lip seal. The three key dimensions are shaft 17 mm, housing 28 mm and height 7.00/12.80 mm. The A 117-Hel designation describes a profile that combines a sealing lip with a reinforced body. The stepped height lets the seal sit in a cavity with a shoulder or in a cover that needs a deeper seat, without changing the outer diameter.

You will find this oil seal in small centrifugal pumps, low-power electric motors, gearboxes, compressors, fans and transmission units. It also appears in machine tools, conveyors and hydraulic systems where a 17 mm shaft turns inside a 28 mm housing. In each case, it holds lubricant in place and keeps dirt out, which helps protect bearings and gears from early wear.

Before installation, confirm that the shaft and housing are clean and free of burrs or scratches. Coat the lip with the same oil or grease used in the equipment, then slide the seal on. Press it in squarely with a tube that contacts the outer diameter, and avoid hitting the lip. Because the height is 7.00/12.80 mm, check the seat so the lip runs centered on the shaft track. If the shaft is worn, a sleeve may be the better option.

When you need a replacement, send the code 6808 or the three dimensions of your current seal: shaft, housing and height. With that information we can look for alternatives in other brands or configurations within the same category. We can also help you choose the lip design and elastomer material based on the fluid and operating temperature, so a hard-to-find part does not leave your equipment down.
