The DBH 6603 radial shaft seal is a lip seal designed for 120 mm rotating shafts, with a 150 mm housing and 12 mm height. Its function is to retain 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 by the designation 6603. According to the product page data, it corresponds to a shaft diameter of 120 mm, a housing of 150 mm and a total height of 12.00 mm. The indicated design is Lx, which defines the lip and outer body configuration. It is a direct replacement part for equipment already using this size, and 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 obtaining the exact size is the only way to keep the assembly running without modifying the housing.

To select a seal correctly, three things must be verified: shaft diameter, housing diameter and height. It is also 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.

If you need a nearby size or an equivalent from another brand, send us the full part number and the shaft, housing and height measurements. With that data we can look for an alternative within the same seal category. We can also advise you if the Lx design is not the one for your application, as long as you tell us which equipment it is fitted to and what type of lubricant it uses.
