What is the difference between a lead screw and a ball screw in a linear actuator?
Release time:

Lead Screws: Use a threaded rod and nut to create motion. They have more friction, which makes them self-locking, meaning they hold their position when the motor is off. However, they are less efficient and wear faster.
Ball Screws: Use recirculating ball bearings between the screw and nut, reducing friction and increasing efficiency. Ball screws are more precise and durable but usually more expensive and require a braking system to maintain position.
