This item is a DBH 6388 radial shaft seal, identified by its part number 6388. Its dimensions are 46 mm shaft diameter (d), 72.87 mm housing diameter (D) and 8.75 mm height (h). The Ls design corresponds to a single lip seal with spring, intended for rotating shafts with lubrication. The DBH nomenclature groups seals with a standard profile for press fitting into a cylindrical housing.

It is used in equipment where lubricant must be retained and dust or water excluded: gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. It also appears in older or imported machines where the exact size is not the usual one and a replacement must be found by dimensions. It is a wear part: when the lip hardens or the shaft is marked, it starts losing oil.

To install it, check that the shaft has no burrs or splines in the lip area and that the housing is clean and free of dents. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do it with a tube or press that bears evenly on the outer diameter, never on the lip. If the shaft is worn, consider a seal with an offset lip. The selection depends on speed, temperature and the type of lubricant.

If you need an equivalent, send us part number 6388 or the dimensions of your old seal: shaft diameter, housing diameter and height. A photo of the part and the housing also works. With that data we review alternatives within the DBH line or from other brands we sell, always confirming against the manufacturer's data sheet before requesting a quote.
