Determining the service or useful life of screw actuators – lead (acme), ball, and roller screws is a fundamental problem that faces many motion-system designers. In a broad sense, a screw’s service ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. Lead screws are one of the most common linear-motion devices, thanks to their low cost and reliability. And recent ...

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 ...

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, ...
