When a rotating shaft needs a dependable barrier between its lubricated interior and the outside, the DBH 6399 oil seal steps in. This radial lip seal presses into the housing cavity and keeps oil or grease where it belongs while blocking dust, water and other contaminants. Its Lx configuration pairs a sealing lip with a metal outer case, making it a common choice for gearboxes, pumps, electric motors and similar equipment.

The seal carries part number 6399 and belongs to the DBH line. Its three key dimensions are a 47.63 mm shaft diameter, a 70.26 mm housing bore and a 16.66 mm overall width. The Lx designation tells you it has a single lip and a metal case, built for rotating shafts that rely on internal lubrication. Before you pull a worn seal, compare these figures with the actual shaft and cavity measurements.

You will typically find a seal this size on transmission shafts in gearboxes, centrifugal pumps, electric motors, mixers and machine tools. In every case it does the same job: hold lubricant inside the assembly and keep out the particles that speed up wear on bearings and gears. It also serves as a secondary closure on gearbox and spindle applications.

Selection and installation call for a close look at the shaft. The lip contact area should be free of burrs, deep scratches or grooves. Lubricate the surface where the lip will ride, then press the seal in squarely to the shaft. Use a tube or shim that pushes on the outer edge, never on the lip itself. If the housing has burrs, clean them before seating the case.

If you need an alternative to the 6399, send the part number, the shaft and housing dimensions, and a photo or sample of the old seal. With that information we can search for equivalents within the DBH line or from other brands we supply. We can also tell you whether the Lx design suits your application or if a different lip style or material would work better.
