"Carbonitrided helical rack" as an alternative to ball screws without stroke limitation.

[Usage Example/Q&A Presentation] High precision and high-speed transport with a cumulative pitch error of 10μm or less! Suitable for drive shafts of machine tools and running axes of robotic transport systems, etc.! *Video available

Our company manufactures and sells "case-hardened gear helical racks" that keep cumulative pitch error below 10μm, enabling high-precision positioning. With high rigidity and low vibration, they can transmit rotation smoothly and at high speeds, making them suitable for drive shafts of machine tools and travel axes of robotic transporters. They can be extended without limit on stroke, and in applications requiring long strokes, using them as a substitute for ball screws can lead to cost reductions. 【Features】 ■ Adopts a global standard twist angle of 19°/31'/42" ■ Entire length can be aligned to an integer ■ Resistant to wear and impact, contributing to the longevity of machinery ■ Can be manufactured to requested lengths and available for purchase from a single unit *For more details, please refer to the materials.
