💡 How do you choose end supports to keep a ballscrew aligned under load?
Quick answer: match pitch, travel length, and support style to your axis load and speed.
* Pitch controls feed rate and torque demand
* Proper end supports keep alignment tight under load
* Good lubrication cuts heat and wear over time

Built to keep motion smooth and accuracy steady during long production runs.
