Q2: How do self-locking linear actuators work?
These actuators typically use a lead screw or ball screw mechanism with a self-locking feature, meaning the screw design resists backdriving (reversal of motion) due to friction or mechanical properties. When the actuator is powered off, the mechanism holds its position without requiring additional brakes or external holding devices, ensuring stability and reducing energy consumption.
Q3: What are the advantages of using self-locking linear actuators in precision engineering?
Position Holding: The primary advantage is their ability to hold precise positions without additional power or braking systems.
