In this paper, the load distribution formula on a ball spline is derived in the case where a radial, a moment and a torque load are simultaneously applied to the ball spline. The fluctuation states of the load distribution and of the maximum distributed load are obtained in accordance with the ball movements in the ball spline and the basic static load ratings are made clear under various applications. The following is a brief summary of the calculation results : (1) The fluctuation state of maximum distributed loads was very extreme and it showed a peak value. Therefore, it is found that the basic static load rating for ball spline is to be decided on the load distribution state corresponding to this peak value of the maximum distributed load. (2) In the case of moment loading the load distribution state in the ball spline became uneven, while in the case of torque loading it became even. As the basic static load rating for the ball spline was dependent on the radial load, however, it was extremely decreased with the increase of the moment loading and/or the torque loading.
