摘要

The bush (6) has an inner bush comprising a bearing seat, and an outer bush partially enclosing the inner bush. The outer and inner bushes have respective materials with different thermal expansion coefficients. The outer and inner bushes are connected with each other by casting, and are casting parts. The outer bush or the inner bush has form-fit elements (22) i.e. teeth, distributed over a periphery of the outer bush or the inner bush, respectively. The teeth extend radially inwardly in a direction of the inner bush or radially outwardly in a direction of the outer bush.
