Ball screw linear actuators

Ball screw linear actuators are mechanical devices that convert rotary motion into linear motion. 

They consist of a reciprocating ball screw, which is a threaded rod with a series of ball bearings that move along the thread, and a motor or other rotary power source that rotates the screw. 

As the screw rotates, the ball bearings move along the thread, causing the screw to move in a linear direction. 

Linear actuators are used in a variety of applications, such as robotics, automation, and manufacturing, where precise and controlled linear motion is required. 

Ball screw linear actuators are known for their high efficiency, accuracy, and reliability, making them a popular choice in many industries.
