The invention discloses a bearing system. The bearing system comprises a vertical box; an inner cavity is fixedly formed in the vertical box; connecting grooves, positioned in the vertical box, symmetrically communicate in the left and right end walls of the inner cavity left and right; a screwing through column is rotationally arranged in the upper and lower end walls of the inner cavity, rotationally penetrates through the upper end wall of the inner cavity, and extends out of external space; an ejector block and a connecting box are arranged on the outer surface of the screwing through column in a threaded fit connection manner; slide connecting rods are symmetrically fixed on the left and right end surfaces of the ejector block left and right, and are slidingly matched and connected with the connecting grooves; slide rods are symmetrically fixed on the left and right end surfaces of the connecting box left and right, and are slidingly matched and connected with the connecting grooves; a transmission cavity is fixedly formed in the ejector block; and an open connecting cavity, opened downwards, is fixedly formed in the lower end surface of the ejector block. The bearing system is simple in structure and convenient to use, and adopts a clamping structure and a sensor induction mode to realize the load measurement of inner and outer rings of bearings to effectively improve thereliability and the practicability.
