Most inexpensive 3D printers use a type of lead screw to move some part of the printer in the vertical direction. A motor turns a threaded rod and that causes a nut to go up or down. The printer part ...

Ball screw mechanisms represent a critical class of precision drive components that convert rotational motion into linear motion by utilising recirculating ball bearings. This conversion is achieved ...

This close-up of the ball contact in a profile projector shows a gothic arch. It consists of at least two radii slightly larger than the ball used, but offset so the raceway touches the ball on both ...

Barnstaple, England-Engineers use ball screws when they want efficient, reliable, and repeatable conversion of rotary to linear motion-characteristics that have made ball screws standard in a wide ...

This file type includes high-resolution graphics and schematics when applicable. Lead screws are one of the most common linear-motion devices, thanks to their low cost and reliability. And recent ...

Global production network: In February, Schaeffler started production of ball screw drives for steering systems at its plant in Xiangtan, China. Credit: Schaeffler. Schaeffler, a German manufacturer ...

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 ...
