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 ...

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, ...

Most inexpensive 3D printers use a type of lead screw to move some part of the printer in the vertical direction. A motor turns a threaded rod and that causes a nut to go up or down. The printer part ...

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 ...

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 ...

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 ...

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, ...
