The DBH 8663 radial shaft seal is a lip seal that prevents oil or grease leaks and the entry of dust and water on rotating shafts. With dimensions of 40 mm shaft, 52 mm housing and 7 mm height, and design Mx, it is press fitted into crankcases, covers and gear reducer boxes. It is a key part for maintaining lubrication and protecting bearings and bushings in industrial equipment.

This DBH 8663 seal has a 40 mm shaft diameter, a 52 mm housing diameter and a 7.00 mm height. Its Mx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The designation 8663 identifies the exact size within the DBH line, and the assembly is press fitted into the housing to seal against the shaft.

It is used in gear reducer boxes, pumps, electric motors, transmission shafts and process equipment. Also in applications exposed to dust, water or chips, such as conveyors, mixers and machine tools. By retaining lubricant and blocking contaminants, it extends the life of bearings and gears and reduces maintenance downtime.

To select it, verify that the shaft and housing dimensions match those of the original seal. The Mx design is suitable for medium speeds and low pressures; if the equipment runs at high peripheral speed or pressure, ask about a reinforced variant. During installation, lubricate the lip, avoid striking it and make sure the shaft has no burrs or wear that could damage the seal.
