Lead Screw Mechanism Self-Locking Calculator

Step 3: Self-Locking Result

• Use an accurate pitch diameter when possible; estimated values reduce judgment accuracy.
• Self-locking depends on lead angle, friction, thread type, materials, lubrication, load, and more. Results are for reference only.
• For ball screw helix angle only: choose known pitch diameter, enter pitch-circle diameter and lead, then read γ.
