What is the difference between driving linear modules with a belt versus a ball screw?

Linear modules can be driven either by a belt or a ball screw. The main difference lies in the drive mechanism and performance. Belt-driven modules typically offer higher speeds and smoother motion, while ball screw-driven modules are more suitable for tasks requiring higher precision and heavier loads.

What are the advantages of linear modules compared to other motion control devices?

Linear modules offer several advantages compared to other types of motion control devices, such as higher precision, smoother motion, and the ability to handle larger loads at higher speeds. Additionally, they are often more compact and easier to install and maintain.
