Title: Ball bearing inspection apparatus

Abstract: A ball bearing inspection apparatus 1 comprising: a rotation shaft3 fitted to one (for example, inner race 7) of inner and outer races 7 and 9 for rotating one race while limiting the movement of one race in an axial direction of the rotation shaft 3; a press plate 13 disposed on an opposite side of the rotation shaft 3 with respect to a ball bearing 5 for pressing the other race (for example, outer race 9) in the axial direction of the rotation shaft 3 while limiting the rotation of the other race; and a press-back plate 33 provided so as to be movable in the axial direction of the rotation shaft 3 for pressing back the other race in a direction reverse to the pressing direction of the press plate 13. Hence, the ball bearing inspection apparatus can inspect a large area of ball surfaces in a short time at one installing try.
