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 ...

Most 3D printers use leadscrews for at least one axis. These are simple devices that are essentially a steel screw thread and a brass nut that travels on it. However, for maximum precision, you’d like ...

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, ...
