Abstract
A method and apparatus for obtaining temperature-independent mounting of a shaft made of a first material having a first coefficient of thermal expansion, in a bearing which interacts with the shaft and which is made of a second material having a second coefficient of thermal expansion, the first coefficient of thermal expansion having a higher value than the second coefficient of thermal expansion, includes arranging on the shaft made of the first material having the first, higher, coefficient of thermal expansion, an outer shell to surround at least the greater part of the shaft's circumferential surface and to be at least partly located outside the area in which the bearing is supported. The outer shell is made of a third material having a third coefficient of thermal expansion which has a lower value than the second coefficient of thermal expansion.
