The DBH 6651 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and stop dust, water or particles from entering. With a 17.46 mm shaft diameter, 27.02 mm housing diameter and 7.30 mm height, and Lz design, it is a replacement part for equipment where axial space is limited and rotation speed demands a flexible, well-seated lip.

This item is a radial shaft seal from the DBH line, identified by code 6651. Its dimensions are 17.46 mm shaft diameter (d), 27.02 mm housing diameter (D) and 7.30 mm height (h). The Lz design corresponds to a seal with a single sealing lip and metal case, intended for press-fit installation in a cylindrical housing. It is a compact-section part, suitable for small-diameter shafts where the seal must take up little width.

It is used in gearboxes, electric motors, pumps, compressors, machine tools and transmission equipment. It also appears in agro-industrial applications and in process equipment where oil or grease must be separated from the environment. Its function is twofold: prevent lubricant leaks to the outside and block the entry of contaminants that wear down bearings and bushings. It is a wear component, so it should be checked at every teardown.

To select it, verify that the shaft diameter and housing diameter match the values in the data sheet. The lip must rest on a surface free of grooves or burrs; if the shaft is scratched, the seal will not seal even if it is new. Before installing, lubricate the lip with the same grease or oil used in the equipment and place the seal perpendicular to the shaft, using a tube or shim that rests on the metal edge, never on the lip. If the housing has a shoulder, respect the seating depth.

If you need a nearby size or an equivalent, send us code 6651 and the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we search the DBH line or another compatible alternative. We can also advise you if the Lz design is not the most suitable for your application and it is worth evaluating another type of lip or material.
