     Note 1: The permissible dynamic torque (T) or permissible dynamic thrust (F) is the value at which the contact surface pressure on the screw tooth surface is 9.8 N/mm2. The maximum axial load (both when stopped and during operation) is set to the dynamic permissible thrust or below, and it must be selected while taking into consideration the desired safety factor.
