Abstract
A combined roller- and slide bearing comprises at least one roller bearing having roller elements disposed between inner and outer bushings thereof and a slide bearing having a lubricating gap defined between inner and outer bushings thereof. The roller bearing and the slide bearing are disposed axially adjacent to each other and have the same rotational axis. The roller bearing and the slide bearing are configured such that the roller bearings elastically deform in response to a radially-acting load, thereby reducing the radial thickness of the lubricating gap in a circumferential portion thereof, because the outer bushing of the slide bearing radially shifts relative to the inner bushing of the slide bearing. In this state, the circumferential portion of the slide bearing having the reduced radial thickness undertakes a load-supporting and bearing function.
