A bearing seat eccentric distance adjusting device comprises a rotary workbench and a concentric spherical mechanism, the concentric spherical mechanism comprises a housing, a moving rod and a plurality of ball rod assemblies, and the bottom end of the moving rod is inserted into the housing and then fixedly connected with the top ends of round rods in the ball rod assemblies. The bottom ends of the round rods penetrate through a fixing plate fixed in the housing and then are fixedly connected with round balls, and the round balls in the multiple ball rod assemblies are evenly arranged on a circle coaxial with the central axis of the moving rod. According to the design, firstly, the bearing seat is placed on the rotary workbench, the lower end of the concentric spherical mechanism extends into an inner hole of the bearing seat, then the concentric spherical mechanism is transversely moved, and the distance between the central axis of the moving rod and the central point of the rotary workbench is adjusted to
