Permissible forces Fx, Fy, Fz and torques Mx, My, Mz

With simultaneously moments on the cylinder this equation must be used in addition to the maximum moments check. In the cushioning phase of the movement additional forces occur and must be considered. Please use our calculation tool for rodless cylinders on the www.boschrexroth.com/pneumatics.
