The DBH 8679 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and exclude contaminants. Its dimensions of 39.4 mm shaft, 63.55 mm housing and 12.70 mm height make it suitable for gearboxes, pumps and rotating equipment where axial space is limited. Its Lx-Bidi design combines a main lip and a secondary lip to improve sealing in both directions of rotation or in the presence of splashes.

This item is a radial shaft seal from the DBH brand, identified with code 8679. Its dimensions are 39.4 mm for the shaft diameter, 63.55 mm for the housing diameter and 12.70 mm total height. The Lx-Bidi design indicates a double-lip configuration, intended to contain lubricant and stop dust or water from entering from the outside. The elastomer and the internal spring are not detailed in this record, so they are confirmed against the manufacturer's data sheet at the time of quoting.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the seal protects the bearings and the lubricant from the environment, extending the service life of the assembly. It is also used on fan shafts, mixers and agricultural or industrial machinery where there is continuous rotation and a need for sealing.

For correct mounting, verify that the shaft and housing are clean, free of burrs and scratches, and lubricate the lip before inserting it. The seal must enter perpendicular to the shaft, without blows that deform the casing. Selection depends on rotation speed, working temperature and the type of fluid to be retained. If the shaft shows wear, consider a repair sleeve or an alternative size to ensure lip contact.

If you need an equivalent seal or a nearby size, send us the 8679 code or the shaft, housing and height dimensions. With that data we look for alternatives in other brands or series that perform the same function. We can also advise you if the mounting space is different or if the Lx-Bidi design does not fit your application. The idea is for you to find the part that truly solves the problem, not just the one listed.
