Ball screw

-Precision Ground Ballscrew: Hiwin Precision Ground Ballscrews are manufactured through the grinding process of the screw spindle. Precision ground ballscrews offer high positioning accuracy and repeatability, smooth motion, and a long service life. These highly efficient ballscrews are an optimal solution for various applications.
-Rolled Ballscrew
: The main differences between rolled ballscrews and ground ballscrews are the manufacturing process, lead error definition, and geometric tolerances. Hiwin Rolled Ballscrews are manufactured through a rolling process rather than a screw shaft grinding process. Rolled ballscrews achieve smooth motion and low friction, can be quickly supplied from stock, and reduce production costs.
-Super S Series
:Super S Series uses a patented design return system, which absorbs ball impact noise to significantly reduce noise intensity, allowing ballscrews to maintain peak performance in harsh environments. The modified return system improves the strength of the return structure, increases the Dm-N value, and reduces the ball nut diameter by 18% to 32%.
-Super T Series
：The circulation path of the Super T Series leaves ball tracks tangential to the PCD and has elements that coordinate with the lead angle of the ballscrew shaft. It is an optimal design that not only reduces noise but also vibration, achieving smooth rotation.
-Miniature Ground Ballscrews
: Hiwin Miniature Ground Ballscrews are manufactured through the grinding process of the screw spindle. Miniature ground ballscrews are compact and ideal for applications with small loads and short strokes. These highly efficient ballscrews offer high positioning accuracy and repeatability, smooth motion, and a long service life.
-R1 Series Rotating Nut
: Hiwin's rotating nut adopts a special end cap design that allows steel balls to circulate within the nut, while featuring an integrated bearing that can fix the ballscrew shaft. This unique design reduces noise generated at high speeds and increases axial load and rigidity.
-Heavy Load Series
: Heavy Load Series offers 2 to 3 times the load capacity of standard ballscrew series. They are suitable for high-speed conditions and feature an enhanced circulation system that can achieve a longer service life.
-Roller Screw
：Roller Screw uses rollers instead of steel balls, which increases the contact area and alleviates stress concentration. It offers 1.5 to 2 times the load capacity of standard ballscrew series, and its enhanced circulation system allows for higher axial loads. It is a screw that achieves ultra-high rigidity and extended service life by incorporating rollers.
