The invention provides a large-size bearing with the center capable of being adjusted. The large-size bearing comprises an annular bearing seat and a plurality of fixed supporting mechanisms. Each fixed supporting mechanism comprises a direction connecting plate, a high-low-position connecting plate, a direction shaft, a small direction shaft bearing, a high-low shaft and a small high-low shaft bearing. According to the large-size bearing with the center capable of being adjusted, the fixed supporting mechanisms are adopted to replace an inner ring stator of a traditional large-size bearing to support a winding barrel of a reconnaissance vehicle mast device, so that the structural mass is greatly reduced; in addition, the fixed supporting mechanisms are connected with the winding barrel through radial groove holes; during mounting, the center can be conveniently adjusted, and the coaxiality requirement is ensured.
