Abstract
A bearing unit includes at least one first ring and at least one second ring, the at least one first ring and the at least one second ring being rotatable relative to each other and defining a bearing interior between them. Each first ring is designed to be attached to a component with a press fit, the component being formed from a first material with a first coefficient of thermal expansion. The first ring(s) is/are formed from a second material with a second coefficient of thermal expansion that is different than the first coefficient of thermal expansion and the first ring(s) are provided, on a side facing the bearing interior, with at least one insert element. The insert element(s) are formed from a third material with a third coefficient of thermal expansion, the third coefficient of thermal expansion being at least as great as the first coefficient of thermal expansion.
