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 special application requirements.
Hiwin has the capability of producing JIS C0 class ground ballscrews, and DIN 5 class (up to 23 microns) for precision rolled ballscrews. Ballscrew O.D. ranging from 4mm to 120mm, and with Dm-N values up to 220,000.
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.
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.
