The invention discloses a steering shaft with a light thrust sliding bearing. The steering shaft comprises universal joint forks, a median segment shaft, thrust sliding bearings, elastic closing rings for the shaft, sliding bearings and sleeved brackets, wherein the median segment shaft is connected with the universal joint forks, the sliding bearings are arranged inside the sleeved brackets, the thrust sliding bearings are in contact with the sliding bearings, and the thrust sliding bearings are made from compounds of metal and plastics. According to the invention, the light thrust sliding bearings which are mixed with plastics and the general sliding bearings are adopted for jointly positioning the steering shaft, and besides, the thrust sliding bearings have the effect of a seal ring, so that the structure of the whole mechanism is simplified, and the weight of the whole mechanism is greatly lighted; besides, compared with a traditional rolling bearing, the friction between a bearing and a shaft is reduced, the situation that noise is generated in the process of operation is avoided, and the service life of the whole mechanism is prolonged.
