In the worlds of Semiconductor manufacturing and Life Sciences, “precise” isn’t good enough, you need to move with the delicacy of a heartbeat.

IKO recognised that traditional ball-screw driven tables eventually hit a physical limit in resolution and smoothness. That is why the company developed the NT Series Nano Linear NT, a compact, linear motor-driven table that replaces mechanical drive components with a direct-drive system. Eliminating the ball screw removes friction, backlash, and wear from the equation.

For clients in metrology and spectroscopy, IKO has found that the NT series offers a level of responsiveness that is simply unreachable with traditional hardware. Because there are no contact points in the drive system, the motion is exceptionally smooth, allowing sub-micron steps without the stick-slip effect. This aligns with the company’s “specify once, fit once” approach: with fewer moving parts to wear out, long-term reliability and TCO are substantially better than those of conventional micro-stages.

• Direct Drive Linear Motor: Eliminates the ball screw and coupling, which means you get zero backlash and extremely high-speed stability.
• High-Resolution Feedback: Equipped with a high-accuracy linear encoder, providing positioning resolutions down to the nanometre level.
• Ultra-Low Profile: The NT…V variation is incredibly compact, which means your engineering team can integrate nano-positioning into even the most space-constrained instruments.
• Cleanroom Ready: With no lubricating grease required for a drive screw, the NT series is inherently cleaner, making it ideal for sensitive vacuum or medical environments.

Engineering teams describe the switch to the NT series as moving from a manual gearbox to an electric drive: silent, instant, and perfectly smooth. IKO frequently hears from teams that struggled with hunting, where the motor cannot settle on the exact position, using ball screws; the NT series snaps to the target and stays there. It is built for applications where “close enough” is never enough.

Are you finding that traditional ball screws are limiting your resolution? Let’s explore how direct-drive technology can sharpen your process.
