The housing i.e. inner housing (3), has two housing portions (3a, 3b) arranged along an axial axle, where the housing portions are axially connected with each other by a heat shrinking process. One of the housing portions has a recess formed in a circumferential direction, and the other housing portion has a projection formed in the direction, where the projection is pressed into the recess. The latter housing portion is arranged behind the former housing portion in a radial direction, where the housing portions are made of chrome steel. An independent claim is also included for a method for manufacturing housing portions.
