This heating can lead to a different downside: constrained duty cycle. If you’ve at any time run a nut along a threaded rod by spinning the rod in a very drill, you’ll get an concept of just how much warmth might be generated by a lead screw. The warmth can easily injury a lead nut, especially a plastic or composite a person. So most lead screws Have a very limited responsibility cycle, to allow warmth time for you to dissipate.
