The DBH 8851/85 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 25 mm shaft diameter, 41 mm housing diameter and 8 mm height, it corresponds to designation A 016. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with shafts of that size.

This item is a radial shaft seal from the DBH line, identified as 8851/85. Its nominal dimensions are 25.00 mm shaft diameter, 41.00 mm housing diameter and 8.00 mm height. The indicated design is A 016, which defines the geometry of the lip and the outer body. The flexible lip runs on the shaft and the outer diameter fits into the housing to prevent oil or grease from escaping outward and contaminants from entering.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, rollers and belt or chain drive equipment. In all cases it serves to retain lubricant at the point where the shaft passes through the housing and to protect bearings or bushings from the entry of dirt. It is a wear part that should be replaced when lubricant leakage or noise at the support appears.

For installation, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip before inserting it and seat the seal with a tube or spacer that presses on the outer edge, never on the lip. Selection depends on shaft speed, operating temperature and the type of lubricant; if the equipment operates with heavy vibration or exposure to dust, a design with an auxiliary lip or dust guard should be evaluated.
