Description

• Precision Ground Ballscrew Hiwin precision ballscrews are made through a grinding process of the screw spindle. Precision ground ballscrews provide high positioning accuracy and repeatability, smooth movement and long service life. These highly efficient ballscrews are a perfect solution for a variety of applications. • Rolled Ballscrew The major 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 which greatly reduces the noise intensity and allows 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 not only reduces the noise level but also 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 load and shorter stroke applications. These highly efficient ballscrews provide high positioning accuracy and repeatability, smooth movement and long service life. • R1 Series Rotating Nut Hiwin’s rotating nut utilizes a special end cap design that allows the steel balls to circulate inside the nut while featuring an integral bearing that allows 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 that are suitable for high speed conditions and are able to achieve a longer service life. • Roller Screw Roller screws use rollers instead of steel balls, which reduce the 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. By incorporating rollers, these screws offer super high rigidity and are able to achieve a longer service life.
