The DBH 6399 radial shaft seal is a lip seal that mounts in the housing of a piece of equipment to retain lubricant and stop dust, water or particles from entering. Its Lx design combines a sealing lip with a metal case that fits into the cavity under pressure. 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 are the values you need to check 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 every case it performs the same function: keeping oil or grease inside the assembly and preventing contaminants from entering that accelerate wear on 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 not have burrs, deep scratches or wear in the lip contact area. The surface where the lip rests is lubricated before fitting the part, and the seal is inserted perpendicular to the shaft, with a tube or sleeve that rests on the outer edge, never on the lip. If the housing has burrs, clean it before seating the case.
