The DBH 6693Pol is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its Kx-Hel design adds a secondary exclusion lip to the main sealing lip, so it handles dusty or wet environments better than a single-lip seal. You will find it in gearboxes, pumps, motors and transmissions where the shaft turns continuously.

This seal carries the reference DBH 6693Pol and measures 52.40 mm at the shaft, 81.00 mm at the housing and 11.50 mm in height. The Kx-Hel designation tells you it has two lips: a main lip for oil or grease retention and an auxiliary lip that blocks particles and water from reaching the bearing. The 6693Pol code is what you use to order the part or to ask for a cross-reference.

Seals of this size and style show up in gearboxes, centrifugal pumps, electric motors, rollers and belt or chain drives. You also see them in agricultural and road machinery, where shafts run in dust or mud. In every case the job is the same: hold the lubricant inside the assembly and keep contamination away from bearings and gears.

Proper installation starts with a clean shaft free of burrs or scratches that could cut the lip. Lubricate the lip before sliding it into place and press the seal in squarely to the shaft. If the housing has a shoulder or radius, set the seal at the correct depth so the lip runs on its intended track. When you select a replacement, match the shaft speed, operating temperature and lubricant type to the seal's capabilities; a lip that is not suited to those conditions will fail early.

If you need a substitute, send the code 6693Pol along with the shaft, housing and height dimensions and the design type you require. That information lets us find the part in the DBH line or suggest a compatible alternative. Telling us the equipment and the lubricant it uses also helps narrow the search.
