This picture may look like a giant shock absorber for an off road vehicle but that is not even close. It is a linear drive component for my HB2 project. It is a nut that is driven left and right when the screw you see traveling through the center is rotated. It converts rotary motion to linear motion. Thus the name, “linear drive component”.
It is an amazing little piece of engineering as it is designed to self adjust as the parts wear to eliminate slop or looseness. This device will probably operate 20 years in the work I will have it perform. Find out more at this link to Kerk Motion Products. Also more info in the workshop.
