This paper deals with the life distribution of ball spline under simultaneously applied radial load and torque. Life test data are plotted by the log-normal, the two-parameter and the three-parameter Weibull distribution function respectively. The rating load is derived from theoretical load distribution in ball spline as well as life test results. The obtained results are as follows: (1) The life distributions of ball spline are conformed well to the three-parameter Weibull distribution function with a Weibull slope m=10/9 introduced minimum life γ. (2) The rating life and rating load for ball spline under the application of combined torque and radial load may be evaluated by the applied torque.
