Abstract
A bearing arrangement for an operating shaft of a multi-pole electric switching device with a chassis formed by central and outer walls that are parallel to each other. The bearing arrangement comprises shaft bearings in the form of half-shells. The central walls, which are designed to accommodate the shaft bearings, are each provided with an open recess at its edge. The recess has one bordering edge that corresponds to the radius and width of a groove located on the outer periphery of the half-shells and another bordering edge that corresponds to the outside diameter of the half-shells. A locking piece is attached to the respective wall and secures the half-shells after they have been assembled on the operating shaft.
