The DBH 6778 radial shaft seal is a lip seal designed for a 41 mm shaft, 56 mm housing and 10 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles, protecting bearings and bushings in rotating equipment. It is a wear part: when the lip hardens or becomes marked, it starts to lose oil and should be replaced before the bearing fails. MR Accesorios Industriales supplies this brand.

The DBH 6778 is a radial shaft seal with the following dimensions: shaft diameter 41 mm, housing diameter 56 mm and height 10 mm. It corresponds to the Mz design, a single-lip configuration with spring that runs on the rotating shaft. The code 6778 identifies the size and design within the DBH line. Before mounting, verify that the shaft and housing match these values, because a seal with a different height or diameter will not seal correctly even if it appears to fit.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil must be separated from the environment. It also appears in agricultural machinery, conveyors and plant equipment where dust or water attack the bearing. In all these cases the seal performs the same function: keeping lubricant in and contamination out, extending bearing life and reducing downtime due to leaks.

To select it, in addition to the dimensions, take into account the shaft speed, working temperature and the fluid to be retained. The Mz design with spring is suitable for rotating shafts with permanent lubrication. During installation, lubricate the lip, verify that the shaft has no burrs or splines and place the seal perpendicular to the shaft, without striking it sideways. If the shaft is worn in the contact area, the new lip will not seal properly: consider a wear sleeve.

If the code 6778 is not exactly the one you need, send us the shaft, housing and height dimensions, the type of fluid and a photo of the old seal. With that data we look for the equivalent in DBH or another brand of the same size. We can also offer you a size if the shaft or housing has tolerance. The more complete the information, the faster we can provide the correct alternative.
