The invention concerns an arrangement for mounting a shaft (1) comprising a shaft journal (8) arranged eccentric to a central longitudinal axis (7) of the shaft (1) on an end portion (6) of the shaft (1), said end portion (6) being supported by a first needle roller bearing (2) in a housing, and said eccentric shaft journal (8) being connected by a second needle roller bearing (9) to a movable part of a connecting structure. According to the invention, the outer ring of each needle roller bearing (2, 9) is made as a deep-drawn bushing (12, 13) which is shaped without chip removal and comprises rims (14, 15, 16, 17) on each side, the diameter d of the inner edge of the outer rims (14, 17) 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 (2, 9), an axial displacement of the shaft (1) is prevented when the fixed bearing (26) fails.
