A large-scale pivot bearing is positioned between a first rotary annular bearing part (1) and a second (2) annular bearing part rotating on a bearing axle (3). The two bearing parts each have circular running surfaces (6a,b;7a,b) in pairs for at least two rows of roller bodies (4,5). Both bearing parts have circular bearing surfaces (15a,b) for transmitting radial forces. The first bearing part is divided into a first (8a) and second (8b) part each possessing a running surface. Through holes (10,11) parallel with the bearing axis and distributed over the periphery of the bearing parts are for fixture screws and go through only the first part of the divided bearing part. The second part of the divided bearing part is in the form of a flat hardened ring with rectangular cross-section enclosing the exterior of the first part and possessing a running surface on its underside for the roller bodies. |
