Is Back-driving Possible in Electro-mechanical Actuators ?

Unless otherwise stated back-driving is possible in all electric linear actuators. Actuators that use a ball screw or roller screw as the lifting screw have an electrical brake (typically motor mounted) to prevent the load from back-driving the actuator. Note if a machine screw actuator is considered self-locking, it may still back-drive if significant vibration and cyclic temperature variations are present.
