1. A steering gear for a steer-by-wire steering system of a motor vehicle, the steering gear comprising:
a coupling rod mounted in a steering gear housing, wherein a threaded spindle is formed on the coupling rod and is surrounded by a spindle nut as part of a spiral gear, wherein the coupling rod is comprised of steel, wherein the steering gear housing is comprised of aluminum; and
a plain bearing that mounts the coupling rod in the steering gear housing such that the coupling rod is displaceable along a longitudinal axis, wherein the plain bearing is configured to compensate for thermal expansions between the steering gear housing and the spindle nut.
