Ball screws are designed for operation under high vacuum. Typical applications include actuators for use in aerospace, electron-beam inspection, lithography, synchrotron research, and nanotechnology ...

Not all ball-screw makers spec products the same way. Stiffness or rigidity is a key factor in evaluating ball-screw drives for specific needs. Rigidity, in this context, describes a ball screw's ...

Most 3D printers use leadscrews for at least one axis. These are simple devices that are essentially a steel screw thread and a brass nut that travels on it. However, for maximum precision, you’d like ...

The inch series precision ground ball screws feature a robust internal recirculation system designed to promote durability and high performance in demanding linear-actuation applications. The ...

Super smooth: the updated linear-shift mechanism from UHV Design exploits a precision slideway to increase the translation speed (Courtesy: UHV Design) UHV Design, which specializes in the design, ...

A lot of the projects we feature here on Hackaday engender the classic “build versus buy” argument. We’ve always been puzzled by that; if anyone can appreciate the sheer joy of making something rather ...
