Abstract

The bearing is particularly for valves in ventilation or air-conditioning conduits, and which rotate on spindles running in the transverse direction. It comprises a tubular section (1) forming a seal in the conduit wall, and either its inner surface, or the outer surface of the spindle accommodated in it are so cambered in the axial direction as to form a peak towards the opposite cylindrical surface. Where the spindle is cambered, this can be achieved by an intermediate tube section fitting on it. The peak can be situated in a plane between the two faces of the conduit wall accommodating the bearing, which can be closed by a base (4) at one end. There can be a notch of annular shape formed in the base so that it will break along this.
