When a packaging motion is air, and when it is a servo
A task comparison of an air cylinder and an electric actuator, using two public articles. Neither one is treated as a replacement for the other.

Packaging lines
A task-by-task comparison of an air cylinder and a servo, and a checklist from the fault signal to the reject ram.
Start here
Decide whether the motion stops at a hard end or must hold a position in the middle. Then check that a reject ram hits the container the sensor saw.
Pneumatic and servo motion puts one published cylinder guide next to one published gripper job. It does not call either a replacement. Reject actuator checklist asks whether the ram pushes the container that failed, using one published inspection station as the example.
