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 ...

Weevils are screwed up. Their legs are, anyway. The beetles are the first animals found to have a screw-and-nut mechanism in their bodies. Poring over CT scans of the Papua New Guinea species ...

It’s easy to cut bolts and small machine screws to length. On the other hand, there isn’t any job so small or simple that it can’t be done wrong, and this is a classic example. Get it right, and you ...

HOW DOES THE CHOICE OF A BALLSCREW OR LEAD SCREW AFFECT PRODUCTIVITY IN A MOTION-CENTRIC AUTOMATION ENVIRONMENT? Woody • THK: Ballscrew technology allows balls to roll between the screw shaft and the ...

For centuries, the conventional lead screw (threaded shaft and nut) was the primary mechanism for converting rotary motion to linear motion. They were inexpensive to manufacture and reliable. Ball ...

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 ...

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, ...
