The invention relates to a steering gear (1) for a steer-by-wire steering device and with a steering rod (4), with a steering rod housing (11), and with a slide bearing bush (12) arranged between the steering rod housing (11) and a steering rod portion (13) of the steering rod (4), wherein the slide bearing bush (12) is fixedly attached to the steering rod housing (11), and the steering rod portion (13) and the slide bearing bush (12) engage with one another in such a way that a rotational movement of the steering rod (4) is blocked and a translational displacement of the steering rod (4) in the axial direction of the central longitudinal axis (5) of the steering rod (4) is allowed. In order to provide a redundancy function in the event of a defect or failure of the slide bearing bush (12), the steering gear (1) is characterized in that the slide bearing bush (12) forms a first anti-rotation component (15) and a second anti-rotation component (16) is arranged between the steering rod housing (11) and the steering rod (4), wherein a fail-safe protection is realized by means of the second anti-rotation component (16) in the event of a defect in the first anti-rotation component (15).
