The utility model belongs to the technical field of bridge supports, and particularly relates to a pressure-bearing spherical support for a bridge expansion joint. According to the main technical scheme, the supporting seat comprises an upper supporting seat body and a lower supporting seat body which are in spherical contact; the lower part of the upper support body is a spherical sliding layer with a concave spherical surface; the upper part of the lower support body is a pressure-bearing body with a convex spherical surface; wherein a limiting mechanism is arranged between the convex spherical surface and the concave spherical surface, the limiting mechanism comprises a central pin shaft and an accommodating hole for limiting the central pin shaft, and the central pin shaft and the accommodating hole are respectively arranged in the concave spherical surface and the convex spherical surface or the central pin shaft and the accommodating hole are respectively arranged in the convex spherical surface and the concave spherical surface. The spherical support has the advantages of being capable of achieving multiple angles and large amplitude of a bridge support, simple in structureand capable of reducing vibration and noise.
