The DBH 6603 radial shaft seal is a lip seal designed for 120 mm rotating shafts, with a 150 mm housing and a 12 mm height. Its function is to retain the lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, so the quality of both parts defines its service life.

This item is a radial shaft seal from the DBH line, identified with the designation 6603. According to the product page data, it corresponds to a shaft of 120 mm diameter, a housing of 150 mm and a total height of 12.00 mm. The indicated design is Lx, which defines the configuration of the lip and the outer body. It is a direct replacement part for equipment that already uses this size, and it is sold as a single unit.

Seals of this type are used in gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing containing lubricant. In industrial plants they appear in conveyors, mixers, mills and machine tools. They are also fitted in older equipment where getting the exact size is the only way to keep the assembly running without modifying the housing.

To select a seal properly, three things must be verified: the shaft diameter, the housing diameter and the height. In addition, it is advisable to check the condition of the running surface: if the shaft has scratches or wear, the new lip will not seal properly. Installation is done with the lip lubricated and a tool that presses evenly on the metal edge, never striking the lip. If the housing has burrs, they must be cleaned before inserting the seal.
