Alignment Table SA...DE/T ｜ Continuous 360° Rotation with Direct Drive Motor

SA...DE/T Alignment Table — continuous 360° rotation using a Direct Drive Motor and IKO Crossed Roller Bearings for precision automation.
🔧 Challenges in Precision Alignment Systems
In semiconductor, display, and inspection industries, traditional rotary tables often suffer from limited rotation range.
This constraint forces engineers to add complex stacked mechanisms, increasing system size, vibration, and loss of alignment accuracy.
⚙️ Root Cause
Conventional gear- or belt-driven systems introduce backlash, vibration, and cable interference, preventing full 360° rotation and degrading positioning precision.
💡 Solution — IKO’s Infinite Rotation Technology
IKO developed the SA Series – Infinite Rotation Type (SA...DE/T) using a Direct Drive Motor and IKO Crossed Roller Bearing.
This enables continuous 360° rotation with micro-radian precision and stable motion through a Full Closed-loop Encoder System.
The Direct Drive eliminates mechanical transmission error, ensuring smooth and backlash-free performance.
🧩 Product Overview — SA...DE/T
The SA...DE/T is a θ-axis rotary table that can be integrated with SA...DE/X linear tables to form a Compact XYθ Alignment Table.
With an ultra-low profile and lightweight design, it offers high responsiveness (up to 720°/s) and positioning accuracy of ±0.5 arc-sec, thanks to its 14,400 pulse/degree encoder.
