The DBH 6682Pol 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. It is press-fitted into the housing and works on the shaft with a flexible lip. It is a wear part that is replaced during preventive maintenance or when a leak appears. MR Accesorios Industriales carries this official brand and advises you so you choose the right size.

This item is a DBH 6682Pol radial shaft seal with the following dimensions: shaft diameter 28 mm, housing diameter 40 mm and height 8.20 mm. The A 156-R-H design corresponds to a single-lip seal with spring, intended for rotating shafts. The 6682Pol nomenclature identifies the part within the DBH line. Always verify these three dimensions before ordering: they are what determine whether the seal seats properly and seals as it should.

Typical applications of a seal of this size include gearboxes, pumps, electric motors, transmission shafts and process equipment. It is generally used where there is a shaft rotating inside a housing and oil or grease must be contained, or the bearing protected from external contamination. It also appears in machine tools, conveyors and food industry equipment, provided the lip material is compatible with the fluid and the working temperature.

To install it, clean the housing and the shaft, verify that there are no burrs or marks that could damage the lip and lubricate the seal before inserting it. The seal must enter perpendicular, without blows that deform the housing. When selecting a replacement, in addition to the dimensions, take into account the shaft speed, the temperature and the type of fluid. If the original seal has a specific design, it is best to respect it so as not to compromise the sealing.
