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 ...

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 file type includes high-resolution graphics and schematics when applicable. Lubricants on ball screws are as important to their performance and life as are their operating loads, speeds, ...

I've used them for ages but never had to buy them. Is there any practical difference in the various sizes of screws and cage nuts? M6 seems to be the prolific choice, but I see 12-24 and 10-32 are ...

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 ...

PROJECT DESCRIPTION: A circuit board inspection OEM had a difficult set of requirements for a two and three axis motion system, most importantly low volume cost, high repeatability, and settling times ...

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, ...

The PRS models, with G5 lead accuracy, are available in screw diameters ranging from 8- to 80-mm, and deliver static load ratings up to 218,000-lbf. Exlar’s PRR models, with G9 lead accuracy, are ...
