Abstract
A bearing for a ball screw drive may include a ball nut that is rotatable about a longitudinal axis and intended to receive a threaded spindle concentrically. The ball nut may be arranged in an inner ring and at least partially in an intermediate ring and an outer ring of the bearing. A belt pulley may be connected to the intermediate ring for rotation therewith, wherein an outer circumferential surface of the inner ring may be convex in some regions and an inner circumferential surface of the intermediate ring may be concave in some regions. The ball nut may be arranged in the bearing so as to be tiltable with respect to the belt pulley. The inner ring may be connected to the ball nut for rotation therewith and may be immovable in an axial direction. The intermediate ring may be connected via spring elements to the inner ring for rotation therewith.
