Abstract
The invention concerns an arrangement for mounting a shaft (,) comprising a shaft journal (,) arranged eccentric to a central longitudinal axis (,) of the shaft (,) on an end portion (,) of the shaft (,), said end portion (,) being supported by a first needle roller bearing (,) in a housing, and said eccentric shaft journal (,) being connected by a second needle roller bearing (,) to a movable part of a connecting structure. According to the invention, the outer ring of each needle roller bearing (,) is made as a deep-drawn bushing (,) which is shaped without chip removal and comprises rims (,) on each side, the diameter d of the inner edge of the outer rims (,) facing away from each other being smaller than the diameter D of the associated inner raceway. Due to this mirror-image arrangement of the two needle roller bearings (,), an axial displacement of the shaft (,) is prevented when the fixed bearing (,) fails.
