The DBH 6808 oil seal is a single-lip radial shaft seal that mounts on a 17 mm shaft and inside a 28 mm housing. Its height of 7.00/12.80 mm and the A 117-Hel design make it suitable for sealing lubricant chambers and stopping the ingress of dust, water or particles in rotating equipment. It is used in pumps, electric motors, gearboxes and transmissions where axial space is limited and a reliable barrier is needed.

The DBH 6808 is a lip-type radial shaft seal, identified by its designation 6808. Its dimensions are 17 mm shaft, 28 mm housing and 7.00/12.80 mm height. The A 117-Hel design corresponds to a profile with a sealing lip and reinforced body, designed to retain lubricant and exclude contaminants on rotating shafts. The stepped height allows it to be seated in cavities with a shoulder or in covers that require a deeper seat without modifying the outer diameter.

Typical applications for this oil seal include small centrifugal pumps, low-power electric motors, gearboxes, compressors, fans and transmission equipment. It is also found in machine tools, conveyors and hydraulic systems where the 17 mm shaft rotates inside a 28 mm housing. In all cases, the oil seal protects bearings and gears from premature wear by keeping lubricant in place and preventing the entry of dirt.

For installation, check that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same oil or grease used in the equipment before sliding it on. Insert the oil seal perpendicularly, without striking the lip, using a tube that bears on the outer diameter. The 7.00/12.80 mm height requires checking the seating so that the lip is centered on the track. If the shaft shows wear, consider a sleeve.

If you need an equivalent, send us the code 6808 or the dimensions of your current oil seal: shaft, housing and height. With that data we look for alternatives in other brands or configurations within the same category. We can also advise you on the lip design and elastomer material according to the fluid and working temperature. The idea is that you don't end up with equipment down for a part you can't find.
