The DBH 6682 is a radial lip seal built for rotating shafts. It keeps lubricant where it belongs and blocks dust, water, and other particles from reaching bearings and bushings. The seal presses into the housing and its flexible lip rides against the shaft. Because it wears over time, it should be swapped out whenever the assembly is opened to maintain a proper seal.

This DBH seal carries part number 6682 and measures 28.00 mm at the shaft, 40.00 mm at the housing, and 8.20 mm in height. Its design code is A 156-R-H, a standard lip configuration for rotating shafts. DBH is one of the seal brands we supply, so the part follows the usual tolerances for the series. Always compare these figures with the housing before you install.

You will find seals like the DBH 6682 in gear reducer boxes, pumps, electric motors, transmission shafts, and process equipment. Their main job is to hold oil or grease around bearings and gears while keeping outside contamination out. They also show up in industrial washing machines, mixers, and conveyors where dust or moisture is a concern. Since the lip runs directly on the shaft, the shaft surface should be ground and free of grooves to avoid lip damage.

When choosing a seal, match the shaft diameter, housing diameter, and height to the original part or the equipment data sheet. Install it with the lip facing the fluid side and the spring pointing inward. Lubricate the lip before insertion and use a tool that will not distort it. If the shaft is worn, a repair sleeve or a seal with an auxiliary lip may be an option.

If you need an equivalent from another brand, we can help. We offer alternatives in different qualities and lip materials.
