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 ...

Can you make a screw out of a piece of paper and pencil? Your friends might think it is magic, but it’s science at work. Here’s an easy experiment that might add a “twist” to your thinking. MATERIALS ...

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 ...

Here’s a little engineering quiz for you: If an app needs to move a 500 kN axial load along a 1,500 mm stroke, is it best to use a roller screw or ball screw? If you instinctively said roller screw, ...
