Inquiry (采购产品): linear actuator Hi there, I am looking for 3 linear rod-style actuators. 2 need to have a maximum length of 18" (fully extended), and the 3rd needs to have a maximum length of 24". Each needs to hold a load of At least 500 lbs. Also, I need the actuators to be able to be extended to locations not only at the zero and max-length positions, but also positions in between while still holding the load. This is a project for NASA and I am hoping you can help. Thanks!
