The invention belongs to the field of bridge accessories, and relates to a spherical bearing capable of realizing large horizontal rotation. The spherical bearing comprises an upper base plate (7), a middle base plate (4) and a lower base plate (1), wherein limiting bosses protruding upwards are arranged at two corresponding ends or the periphery of the lower base plate (1); gaps are formed between the limiting bosses and the upper base plate (7); lantern rings (8) are arranged in the gaps between the limited bosses and the upper base plate (7); the outer walls of the lantern rings (8) matched with the limited bosses are planes; stainless steel guiding sliding plates (10) stuck on and covering the limiting bosses and sliding plates (9) embedded on the outer walls of the lantern rings form sliding friction pairs; cover plates (11) used for limiting the lantern rings to rotate in the vertical direction are arranged above the lantern rings (8); and the cover plates (11) are fixed on the top surfaces of the limiting bosses. The rotating constraint of the spherical bearing on the horizontal plane is released, so that the spherical bearing has a function of rotating in the horizontal plane.
