HIWIN is a Taiwanese company known globally for its linear motion products, especially ball screws and linear guideways. A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with very high efficiency and precision. HIWIN ball screws are used widely in CNC machinery, automation systems, and robotics for smooth, precise, and low-friction movement. 🧩 Components of a Ball Screw Screw Shaft – A threaded shaft that works like a screw. Ball Nut – Contains recirculating balls that travel in the grooves of the screw. Balls – Hardened steel or ceramic balls reduce friction by rolling rather than sliding. Return System – Recycles the balls after one pass through the nut. 🔍 Key Features of HIWIN Ball Screws Feature Description High Precision Manufactured with tight tolerances for micron-level accuracy. Low Friction Rolling motion reduces energy loss and wear. Long Service Life Made from high-grade steel with excellent surface hardness. High Load Capacity Designed to support large axial loads. Smooth Motion Minimizes vibration and backlash. Various Preload Options For stiffness and anti-backlash applications. 🏗️ Types of HIWIN Ball Screws Type Description Application Ground Ball Screws Very high precision, smooth finish, tighter tolerances. CNC machines, precision instruments. Rolled Ball Screws Economical, slightly less precise, but still high performance. Automation, general machinery. Miniature Ball Screws Compact, for small or delicate machines. Medical devices, micro machinery. High-Lead Ball Screws Faster travel speed with lower turns. High-speed applications like pick-and-place machines. 🧰 Applications CNC Machines (mills, lathes, routers) Semiconductor machinery Medical devices 3D printers Robotics Aerospace and defense systems Injection molding machines ⚖️ Comparison: HIWIN vs Others Brand Strengths HIWIN Great price-performance ratio, good global support, reliable quality.
