Linear Guide & Ball Screw Bearings
Linear guides consist of guide rails, sliders, rolling elements, and sealing components to provide accurate and smooth linear guidance. Ball screws include screw shafts, nuts, and recirculating balls to convert rotary motion into precise linear movement. Together, they deliver high positioning accuracy, low friction, and reliable motion control for automation, machine tools, robotics, and precision industrial applications.

Classification of Linear Guide & Ball Screw Bearings
Ball Linear Guides
Ball linear guides use recirculating steel balls between guide rails and sliders to achieve smooth and accurate linear motion. Furthermore, they provide low friction, high positioning accuracy, and reliable load support for automation equipment, machine tools, semiconductor systems, and precision machinery.
Roller Linear Guides
Roller linear guides use cylindrical rollers between rails and sliders to achieve higher rigidity and load capacity than ball designs. Therefore, they are suitable for heavy-duty applications requiring stable movement, accurate positioning, and long-term reliability, including machine tools, industrial automation, and advanced manufacturing systems.
Miniature Linear Guides
Miniature linear guides feature compact rails and sliders designed for limited installation spaces. Moreover, they provide precise motion control, low friction, and reliable performance for small automation equipment, medical devices, semiconductor systems, and precision instruments requiring compact linear movement solutions.
Ball Screws
Ball screws use screw shafts, nuts, and recirculating balls to convert rotary motion into accurate linear movement. In addition, they provide high efficiency, low friction, and precise positioning performance for CNC machines, automation equipment, robotics, and industrial motion control systems.
