The ball screw is one of those ancient inventions that gets put through new paces each generation. It’s a deceptively simple, highly effective mechanical device that enables efficient linear movement from rotational motion. It’s utilized in devices like anti-lock brake systems, airplanes, CNC machines, and even robots. They are manufactured by companies like Dynatect.

Ball screws are much more efficient ways of moving loads in a straight line than their counterparts, like hydraulics or pneumatics. They output 90% of the energy applied to them, create minimal friction, and negligible little thermal effects. Even better, their construction makes it impossible for them to catch fire, which is ideal for commercial and military aircrafts.
