The invention discloses a bearing ball loader, comprising a base; a fixed post is fixed at the top of the base, a top plate is fixed to the top of the fixed post, the fixed post is sleeved with a rotary table, a mounting shell is fixed to the top of the rotary table, a hollow T-shaped block positioned below the bottom of the top plate is fixed to the top of the mounting shell, both the mounting shell and the hollow T-shaped block rotationally sleeve the fixed post, a driving motor is fixed to one side of the top plate close to the base, a bevel gear is fixed to an output shaft of the driving motor, and a bevel gear ring is in engaged connection with the bevel gear. Through the coordinated use of a hydraulic cylinder, a connection block, a spring, a fixing plate, a buffer shell, sharing posts and other structures, balls can be shared, impact movement of the sharing posts can be buffered to avoid breakage of the sharing posts during sharing of the balls, and the bearing ball loader is flexible to use.
