Slide rail system capable of utilizing long stroke during logistics carrying

The utility model belongs to the technical field of sliding rails, and discloses a sliding rail system capable of utilizing a long stroke during logistics transportation, which comprises an upper sliding rail component, a lower sliding rail component and an upper sliding rail component, the upper sliding rail component is arranged on the uppermost portion, the middle sliding rail component is arranged in the middle, the lower sliding rail component is arranged on the lowermost portion, the upper sliding rail component, the middle sliding rail component and the lower sliding rail component form a combination, and all sliding motions are achieved through bearings and engineering plastics. According to the linear guide rail for the linear motion, the interval between the bearings is minimized, the linear guide rail is designed to bear the load of an integrated load at a certain height, and the problems that an existing common linear guide rail for the linear motion is stuck during the linear motion, so that a sl
