How to Size and Select Ball Screws: An Engineer's Guide

Here's how to calculate these speed factors: It's important to remember that you'll need to take the lesser of the two speed limitations in your final screw selection. Critical speed is a result of physics alone. However, there are a few things you can do to make sure that the screw speed remains outside the critical speed range.
