Frequently Asked Questions (FAQs)
1. Is a lead screw linear?
Lead screws are links between different areas in a mechanism and they are used to create linear motion from rotational motion.
2. What type of motion is a lead screw?
A lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them.
3. Can lead screws be back driven?
Lead screws and ball screws have different tendencies to back drive—lead screws typically have a very low chance of back driving, whereas ball screws are more likely to allow the load to fall. This disparity comes down to efficiency.
4. How accurate are lead screws?
Metric Lead Screws 25 Revolutions X 12 mm per revolution = 300 mm of travel with a Lead Accuracy of ±100 µm per 300mm, actual travel could be from 299.9 mm to 300.1 mm.
