The DBH 6682 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that could damage bearings and bushings. With dimensions of 28 mm shaft, 40 mm housing and 8.20 mm height, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a wear part that should be replaced at every teardown to ensure the tightness of the assembly.

This item is a DBH radial shaft seal, identified by part number 6682. Its dimensions are 28.00 mm shaft diameter (d), 40.00 mm housing diameter (D) and 8.20 mm height (h). The design indicated is A 156-R-H, which corresponds to a seal with a sealing lip and a standard configuration for rotating shafts. The DBH brand is a brand sold by MR, so the part meets the usual tolerances of the series. It is recommended to verify these dimensions against the housing before installation.

Radial shaft seals such as the DBH 6682 are used in gear reducer boxes, pumps, electric motors, transmission shafts and process equipment. Their main application is to contain oil or grease in bearings and gears, protecting them from external contamination. They are also used in industrial washing machines, mixers and conveyors, where dust or moisture is present. In all cases, the seal runs in direct contact with the shaft, so its surface must be ground and free of grooves to avoid damaging the lip.

To correctly select a seal, take into account the shaft diameter, the housing diameter and the height. These dimensions must match those of the original seal or the equipment data sheet. Installation is done with the lip facing the side of the fluid to be retained and with the spring facing inward. It is essential to lubricate the lip before inserting it and to use an installation tool that does not deform it. If the shaft shows wear, consider a repair sleeve or a seal with an auxiliary lip.
