Linear slides are mechanical devices that allow smooth, straight-line movement along a fixed path. They are commonly used in various applications, such as 3D printers, CNC machines, and robotics, to enable precise positioning and movement of components. Linear slides typically consist of a rail and a sliding block, which can move back and forth along the rail. These slides can be made from different materials, including aluminum and steel, and may feature ball bearings or other mechanisms to reduce friction. Their design ensures stability and accuracy, making them essential for tasks that require consistent and reliable motion in industrial and engineering settings.
