Awesome! Im building a crane for my tamiya truck trailer. Where I can find the ball screw with the nut ? Or if you can also tell me the dimension of that screw. Thanks!
The system was built for me by a friend of mine. He used a acme thread rod I think 12tpi. The end of shaft is cut down to fit a small roller bearing. The nut is homemade and fitted with a pin on each side to fit the yoke.
Thanks for commenting. There are many strength motors to chose from but it's the thread pitch on the shaft that really determines The power and speed of the mechanism. Here is a great site for various motors and gear drives www.robotshop.com/en/motors-actuators.html
Jeep Lovers . I'll try and get some pics for you this weekend. In the meantime check out this video which does show the tube and nut on the threaded rod. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XqReoXCzzw0.html
