Axis Sizing

Horizontal Linear Motion With Ball Screw – 1

Guide, Ball Screw and Servo Motor Sizing

Today, we are going to learn basic knowledge of how to choose products for horizontal linear axis. Imagine that, this calculation can be Y axis of cnc router or X axis of big 3D printer.

I’m using Yaskawa SigmaJunmaSize+ and THK Life Calculator applications.

Suppose we have a 2000 kg load for the axis that will work horizontally. Let’s consider it as 4 linear guides-2 rails, and the ball screw as the drive element.

lineer calculation steps

The values we want to achieve in the sample application are as shown below.

Max speed: 250mm/sec

Stroke : 2000mm
