Hiwin Ball Screws
Ballscrews consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. Ballscrews convert rotary motion into linear motion and are most commonly used in industrial machinery and precision machines. Hiwin Corporation provides a wide range of ballscrew configurations to satisfy your unique application requirements. Hiwin can produce JIS C0 class ground ballscrews and DIN 5 class (up to 23 microns) for precision rolled ballscrews. Ballscrew O.D. ranges from 4mm to 120mm, with Dm-N values up to 220,000.
Precision Ground Ballscrew
Hiwin precision ballscrews are made through a grinding process of the screw spindle. Precision ground ballscrews provide high positioning accuracy, repeatability, smooth movement, and long service life. These highly efficient ballscrews are a perfect solution for a variety of applications.
Rolled Ballscrew
The significant differences between a rolled and ground ballscrew are the manufacturing process, the lead error definition, and geometrical tolerances. Hiwin rolled ballscrews are made through a rolling process of the screw spindle instead of a grinding process. Rolled ballscrews provide smooth movement and low friction, which can be supplied quickly from stock at a lower production cost.
Super S Series
The Super S series uses a patented design return system that can absorb ball impact noise, significantly reducing the noise intensity and allowing the ballscrew to sustain peak performance in rigorous environments. The modified return system improves the strength of the return structure, which increases the Dm-N value and reduces the ball nut diameter by 18%-32%.
Super T Series
The Super T series circulation path has the elements leaving the ball track tangential to the PCD and coordinating with the lead angle of the ballscrew shafting. This optimal design reduces the noise level and vibrations leading to smoother rotation.
Miniature Ground Ballscrews
Hiwin miniature ground ballscrews are made through a grinding process of the screw spindle. Miniature ground ballscrews are compact, perfect for those smaller loads and shorter stroke applications. These highly efficient ballscrews provide high positioning accuracy, repeatability, smooth movement, and long service life.
R1 Series Rotating Nut
Hiwin's rotating nut utilizes a unique end cap design that allows the steel balls to circulate inside the nut while featuring an integral bearing that enables the ballscrew shaft to be fixed. This unique design reduces noise generated at high speeds and offers higher axial loading and stiffness.
Heavy Load Series
Heavy load ballscrews offer 2-3 times higher loading capacity than a standard ballscrew series. They have reinforced circulation systems suitable for high-speed conditions and can achieve a longer service life.
Roller Screw
Roller screws use rollers instead of steel balls, reducing stress concentration due to the greater contact surface area. They offer 1.5-2 times higher loading capacity than a standard ballscrew series and are capable of higher axial loading due to the reinforced circulation system. These screws provide super high rigidity and can achieve a longer service life by incorporating rollers.
