ROTARY BALL SPLINE OPERATING CONDITIONS The performance of the rotary ball spline is affected by the operating conditions of the application. The operating conditions should therefore be carefully taken into consideration. Operating Temperature Resin retainers are used in the rotary ball spline, so the operating temperature should never exceed 80℃. Dust Prevention Foreign particles or dust in the rotary ball spline nut affects the motion accuracy and shortens the life time. Standard seals will perform well for dust prevention under normal operating conditions, however, in a harsh environment it is necessary to attach bellows or protective covers.
