Abstract: A bearing unit is disclosed, which includes a new labyrinth sealing device designed for use in the ventilation industry that prevents entry of contaminants therein. The sealing device according to the present disclosure provides a “contactless” sealing device, i.e. one without contacting elements (for example elastomer lips); and a bearing unit with a low frictional torque, due only to the internal geometry and the efficiency of the lubricant, but certainly without any contribution from the sealing devices.
