The DBH 6866 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its standard dimensions — 18.80 mm shaft, 27.00 mm housing and 4.76 mm height — make it suitable for compact equipment where space is critical. It is press-fitted into the housing and runs against the shaft, creating a dynamic barrier that extends the service life of bearings and bushings. MR Accesorios Industriales supplies this official brand for industrial and maintenance applications.

This item is a DBH brand radial shaft seal, designation 6866, with the following dimensions: shaft diameter 18.8 mm, housing diameter 27 mm and height 4.76 mm. The Lt design corresponds to a single-lip configuration with spring, intended for rotating shafts lubricated with oil or grease. The 6866 nomenclature identifies the exact dimensional combination, so it must not be confused with seals of similar dimensions. The lip elastomer and the metal case are bonded into a rigid unit that is press-fitted into place.

Typical applications for this seal include small gearboxes, centrifugal pumps, low-power electric motors, gear reducers and transmission equipment. It is also used in agricultural machinery, conveyors and hydraulic systems where lubricant must be contained and dust or water ingress prevented. Because of its compact size, it is common in assemblies where axial space is limited and reliable sealing is required at moderate speeds.

To select this seal correctly, verify that the shaft diameter is within the recommended tolerance and that the housing has the appropriate surface finish. Installation must be done with a uniform pressure tool, lubricating the lip and avoiding impacts that could damage it. Shaft runout and operating temperature affect service life: if the equipment runs at high temperature or high peripheral speeds, consider an alternative compound. Always compare the full designation before replacing.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the original code, a photo of the part and the dimensions measured with a caliper. With that data we can search our seals and radial shaft seals line for the option that best fits, whether from the same brand or another that performs the function. We can also advise you on the most suitable lip design according to the type of lubricant and the working conditions.
