Disclosed is a bearing unit (6) having at least one first ring (8) and at least one second ring, which are rotatable relative to each other and define a bearing interior (12) therebetween, the at least one first ring (8) being designed to be attached to a component part (2) by means of a press-fit, the at least one second ring (8) being designed to be connected to the component part (2) by means of a press-fit, and the at least one second ring (8) being designed to be connected to the component part (2) by means of a press-fit. The component part (2) is formed from a first material having a first coefficient of thermal expansion, the at least one first ring (8) is formed from a second material having a second coefficient of thermal expansion, the second coefficient of thermal expansion differing from the first coefficient of thermal expansion, the at least one first ring (8) is provided with at least one insert element (14-1, 14-2, 14-3) on the side facing the bearing interior (12), the at least one insert element (14-1, 14-2, 14-3) is formed from a third material having a third coefficient of thermal expansion, which is substantially at least as high as the first coefficient of thermal expansion.
