The DBH 6399 radial shaft seal is a lip seal that is mounted in the housing of a piece of equipment to retain lubricant and stop the entry of dust, water or particles. Its Lx design combines a sealing lip with a metal body that press-fits into the cavity. It is used in gearboxes, pumps, electric motors and rotating shafts in general, where a reliable barrier is needed between the lubricated interior and the environment.

This item is a DBH 6399 radial shaft seal, identified by part number 6399. Its dimensions are 47.63 mm shaft diameter, 70.26 mm housing diameter and 16.66 mm height. The Lx design corresponds to a single lip configuration with a metal case, intended for rotating shafts with internal lubrication. These values are what you need to verify against the shaft and the cavity before replacing a worn seal.

Typical applications for a seal of this size appear in equipment with transmission shafts: gearboxes, centrifugal pumps, electric motors, mixers and machine tools. In all cases it performs the same function: keeping the oil or grease inside the assembly and preventing contaminants from entering that accelerate the wear of bearings and gears. It is also used as a secondary closure in gearboxes and spindles.

To select and install a radial shaft seal, it is advisable to check the condition of the shaft: it must have no burrs, deep scratches or wear in the lip contact area. The surface where the lip rests is lubricated before placing the part, and the seal is inserted perpendicular to the shaft, with a tube or shim that bears on the outer edge, never on the lip. If the housing has burrs, it is cleaned before seating the case.

If you need an equivalent to the 6399, send us the part number, the shaft and housing dimensions, and a photo or sample of the old seal. With that data we look for alternatives within the DBH line or from other brands we sell. We can also advise you if the Lx design is not suitable for your application and a different type of lip or material is needed.
