Abstract (en)
A device for rotatably supporting a section of a shaft (4) of a roller (2) of a conveying system in a bath of an apparatus for wet-chemical treatment of workpieces comprises at least one body (14). A space for receiving the shaft section is formed in the at least one body (14). The space comprises a first section (17) having a cross-section, centred on a reference axis (15), of which a perimeter lies on a circle over at least a majority of the perimeter; and a second section (18), extending in axial direction from the first section (17) to an axial end of the space. The second section (18) has, at multiple, e.g. all, axial positions, a respective cross-section of which a boundary, at at least one particular angular position (φ<sub>0</sub>), is at a radial distance to the reference axis (15) equal to a length (Ri) of the radius of the circle and has a radius of curvature extending from the reference axis (15) to the boundary. The respective cross-sections of the second section (18) have, over at least a range of angular positions ([-φ<sub>1</sub>,φ<sub>1</sub>]) other than the particular angular positions (φ<sub>0</sub>), a radial extent from the reference axis (15) that is increased with respect to the radial extent of the cross-section of the first section (17) at corresponding angular positions.
