Linear guides are mechanical components that allow smooth and precise movement along a straight path. They are commonly used in machinery and automation systems to support and guide moving parts, ensuring accurate positioning and reduced friction. Linear guides typically consist of a rail and a sliding block, which can move back and forth along the rail. These guides are essential in various applications, including 3D printers, CNC machines, and robotic arms. By providing stability and reducing wear, linear guides enhance the performance and longevity of equipment, making them a vital part of modern engineering and manufacturing processes.
