摘要： A device for producing a releasable clearance-free position of a rolling bearing, having a rolling bearing which has an outer ring, an inner ring mounted on a shaft and a plurality of rolling elements arranged between the inner ring and the outer ring, and having a tensioning device mounted on the circumference of the rolling bearing outer ring for generating a radial preload which is uniform over the outer circumference of the rolling bearing outer ring between the tensioning device and the rolling bearing outer ring, wherein the tensioning device has an axially adjustable tensioning element which can be brought into a first alignment in which the rolling bearing has play, and which can be brought into a second alignment in which the rolling bearing is free of play. A corresponding method is also described.
