The Ball Screw design is unique in the field of screws, nuts and bolts.
It consists of a long threaded rod, known as the shaft, that is crafted to have its thread precisely spaced tightly together. The most complex portion of this two-part system is the screw element. The screw acts as a nut that goes over the threaded shaft but is different from traditional nuts because it is a self-contained unit with hundreds of tiny steel balls aligned inside.
When the screw is placed over the threaded shaft, the balls easily roll down the threads.
