A ball screw converts rotary motion into precise linear motion using recirculating ball bearings between the screw shaft and nut. Compared with lead screws, ball screw assemblies provide higher efficiency, lower friction, minimal backlash, and superior positioning accuracy—making them essential for CNC machines, robotics, and industrial automation systems.

A linear guide is a precision mechanical component that enables smooth, accurate linear motion by guiding a carriage along a hardened rail with recirculating ball or roller bearings. It provides high load capacity, rigidity, and positioning accuracy, making it essential for CNC machines, automation systems, robotics, and industrial machinery.
