The DBH 6680Pol radial shaft seal is a lip seal that stops lubricant from escaping and blocks the ingress of dust, water or particles in equipment with a rotating shaft. It is press-fitted into the housing and runs on the rotating shaft, with dimensions of 43.40 mm shaft, 56.10 mm housing and 9.00 mm height. It is a wear part: when oil loss appears, it should be replaced with an equivalent one.

This DBH 6680Pol oil seal has a shaft diameter of 43.4 mm, a housing diameter of 56.1 mm and a height of 9.00 mm. Its A 083-R-H design corresponds to a single-lip radial shaft seal with a reinforcing spring, intended for rotating lubricated shafts. The code nomenclature makes it quick to locate in the catalogue and compare against the part you are removing from the equipment. Before ordering, check the three dimensions with a caliper: they determine whether it fits or not.

Typical applications for a seal of this size are gearboxes, pumps, electric motors, rollers and power transmission equipment where the shaft rotates inside a fixed housing. It also appears in agricultural machinery, conveyors and process equipment. In all cases it performs the same function: retaining the oil or grease on the inner side and stopping external contamination. If the seal works at high temperature or with a lot of dust, it is advisable to check the condition of the lip more frequently.

For installation, clean the housing and the shaft, check that there are no burrs or drag marks and lubricate the lip before seating the part. The seal is positioned perpendicular to the shaft and inserted evenly, without striking the lip or deforming the internal spring. If the shaft shows wear or a groove, the new lip will not seal properly: in that case consider a wear sleeve or a different shaft size. The 9.00 mm height must match the usable depth of the housing.

If you cannot find the code 6680Pol or need a nearby size, send us the shaft, housing and height dimensions along with a photo of the old part. With that data we look for the equivalent in the DBH line or in another brand we carry, always respecting the A 083-R-H design and the lip type. We can also advise you if the original seal came with a special geometry, such as a double lip or an external dust guard.
