John, Thanks for the offer. Unfortunately the customer wants to use true linear servo motor (like below), which is different than a servo actuator.
http://www.kollmorgen.com/en-us/products/motors/direct_drive_linear_motors/ They are crazy expensive. I'm just going to advise them to go back and look at the Parker pricing that they had before and use that as a reference to see if they can afford to use linear servos on their next machine. I know they don't have the budget to use linear servos., but they think that since they are a high tech device that linear servos, like flat panel TVs and computers, have probably fallen in price.
