This conventional double nut has a split spacer that can be removed for grinding to adjust the preload. Fitting keys prevent the nuts from turning relative to each other. The size of the nuts, mainly ...

Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...

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 ...

We’ve got mixed feelings about a new video from [AndysMachines] that details how he makes custom ball screws. On the one hand, there’s almost zero chance that we’ll ever have an opportunity to put ...

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 ...
