Non Captive Lead Screw Actuators

We're expanding our line of lead screw motors actuators to include not only our external versions, but now to include the Non-Captive family as well. Different diameters, different leads that you can get for the screws and things that fill out the full range of the product. What makes the Non-Captive actuator unique, is that it allows the screw to pass completely through the motor. People will use this in places where they need shorter stroke applications. The screw ends are typically fixed, and then the motor will be what moves, so you'll mount your load here, your payload, your gripper, or whatever it is your moving. You'll mount to the motor and then that provides the motion. You'll notice also that there is a little bit of axial motion in the screw and you'll often see these with some sort of linear guidance attached to it that will stiffen the entire assembly and then increase your load capacity as well. The screws are rolled right here at PBC Linear we hold tolerances of three-thousandths of an inch per foot as far as the lead accuracy. That's three times better than the published specifications of leading competitors. In Addition to that, you'll notice this nut here has a band around it. A spring around there, most Non-Captives don't have any king of anti-backlash control Where here, with this band, you get continuous force closing the nut down onto the screw and you get anti-backlash capabilities that are 2 to 3 times better than competitive products. The result is a system that's going to give you the highest repeatability and highest accuracy in a Non-Captive actuator.
