Avoid cutting structural screws or lag bolts shorter, as this can reduce load-bearing capacity. A shorter screw means fewer threads to bite into the material and more weight distributed over a ...

The bearings actually squeeze the rod a little bit, making a temporary indentation in the surface that works just like a screw thread would. As the bearings roll on, the rod bounces back to its ...

The critical speed of the ball screw, which depends on the bearing arrangement and the ball nut, constrains the travel rate. Ball nuts have an additional speed limitation due to the maximum ...
