Please Help *** Need Advice On Motor Selection***

The above link shows what I think is a pnuematic cylinder, pressing the primer (center of spent bullet casing out) for reloading purposes. This process is time consuming when done by hand, and the equipment shown in video is way to expensive for this task.  Any chance someone might be able to tell me what type of motor,servo,actuator, or other device I need please?  I would like it to be close to the speed of the one in video, and would need to apply at the very least 5 lbs of force, or more. I can most likely design the contraption, I just need a motor to design it with it around.   If you or someone you know might be able to answer this question, it would be greatly appreciated.  Many thanks, JR
