Optimized design for high reliability

Through use of computer simulation and FEM analysis,the cool type ballscrew features excellent thermalprotection and high reliability.

Promote higher speed rotation and extra highDm-N value (up to 200,000)

Cool type ballscrews will eliminate high-speed rotationaftereffect, i. e., thermal problems, and promote higherspeed rotation.

Prevent thermal distortion

Optimized heat transfer design minimizes heatgeneration and prevents thermal distortion.

Strengthen durability

When operating repeatedly, friction between ballscauses heat generation, It may cause oxidization anddecarburization of the rolling elements, which willaffect service life of ballscrews. Cool type ballscrewswill strengthen durability under a cooling environment.

Extended lubricant life cycle

When using lubrication, minimum heat generationfurther inhibits deterioration in the quality oflubrication and extends the lubricant life cycle.

Higher feeding accuracy

Cooling effect of cool type ballscrew will stabilizeagainst thermal expansion and equalize feedingaccuracy.


Electric-driven injection machines, presses, power units and other replaceable hydrauilc drives.

Ballscrews,also called a ball bearing screws, recirculating ballscrews, etc.,consist of a screw spindle and a nut integrated with balls and the balls’return mechanism, return tubes or return caps. Ballscrews are the most common type of screws used in industrial machinery and precision machines. The primary function of a ballscrew is to convert rotary motion to linear motion or torque to thrust, and vice versa,with the features of high accuracy,reversibility and efficiency. HIWIN provides a wide range of ballscrews to satisfy your special requirements.

The combination of state-of-the-art machining technology, manufacturing experiences, and engineering expertise makes HIWIN ballscrew users “High-Tech Winners”.HIWIN uses precise procedures to create exact groove profiles, either by grinding or precision rolling. Accurate heat treatment is also used to ensure the hardness of our ballscrews. These result in maximum load capacity and service life.

HIWIN precision ballscrews provide the most smooth and accurate movement, together with low drive torque, high stiffness and quiet motion with predictable lengthened service life. HIWIN rolled ballscrews also provide smooth movement and long life for general applications with less precision in lower price.HIWIN has modern facilities, highly skilled engineers, quality manufacturing and assembly processes, and uses quality materials to meet your special requirements.

It is our pleasure to provide you with the technical information and selection procedure to choose the right ballscrews for your applications through this catalogue.
