The DBH 6818 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and stop dust, water or particles from entering. Its dimensions of 28.60 mm shaft, 41.25 mm housing and 10.50 mm height place it in small and medium-sized transmission equipment and pumps. It is a wear part: when the lip hardens or gets marked, oil loss begins and it should be replaced.

This item is a shaft seal with an Mx design, with the dimensions shown on its product page: 28.60 mm shaft diameter, 41.25 mm housing diameter and 10.50 mm height. The Mx design corresponds to a single-lip seal with a metal case and elastomeric lip, intended for rotating shafts with lubrication. The designation 6818 is the code that identifies this size within the DBH line, and it is the data worth having on hand when ordering it.

It is used in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing and the oil must be separated from the environment. It also appears in agricultural machinery, conveyors and process equipment. In all those cases it performs the same function: keeping lubricant in and contaminants out, extending the life of bearings and gears.

To install it, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. Lubricate the lip before inserting the seal and do it with a flat pusher so as not to deform it. If the shaft shows a deep groove, consider a neighboring size or a seal with the lip in another position. The selection depends on the type of lubricant, the speed and the working temperature.

If you need an equivalent or a close size, send us the code 6818 together with the shaft, housing and height dimensions, and the type of equipment where it is mounted. With that data we can look for an alternative within the DBH line or other brands we carry. A photo of the old seal and the housing also helps, especially when the original code can no longer be read.

MR Accesorios Industriales carries the DBH brand as an official brand. If you want to inquire about this size or a neighboring one, write to us on WhatsApp with the code 6818 and we will reply with the quote.
