They hold together everything from the most delicate watch to the largest bridge. The world is literally kept from coming apart by screws and bolts, and yet we don’t often give a thought to these ...

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 ...

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 ...

At one time there was no question about how best to close a wine bottle; you simply put a cork in it. Today, winemakers have more choices. Besides natural cork, the options include synthetic stopper, ...

Add articles to your saved list and come back to them anytime. Well, at least you managed to open the bottles. That’s another problem with screw-caps: sometimes they’re impossible to open at all – ...

Planetary roller screw mechanisms (PRSMs) are advanced mechanical devices that convert rotational motion into precise linear displacement. Their design capitalises on an array of rolling elements ...
