RSMT Series
The RSMT series is a high‑precision 360° continuous rotary stage powered by a direct‑drive motor with precision ball bearings, delivering excellent dynamic performance and positioning accuracy. Featuring outstanding industrial design, it offers table diameters of 100 mm, 150 mm, 200 mm, and 260 mm. Equipped with high‑precision circular grating feedback, it achieves positioning accuracy of ±2.5 arcsec and repeatability below ±1.0 arcsec, with a maximum load capacity of 200 kg—demonstrating outstanding mechanical performance.
The RSMT series features a large‑diameter dual‑bearing design that ensures minimal tilt error, high system stiffness, and excellent repeatability—without performance degradation even under heavy loads. With linear amplifiers in a vibration‑isolated laboratory environment, it achieves in‑position stability and minimum step size below 0.05 arcsec.
The RSMT series offers flexible configuration options, including various table diameters, custom mounting hole patterns, and adjustable stage heights. Thanks to its high accuracy, repeatability, and load capacity, the RSMT is widely used in testing MEMS, gyroscopes, avionics, accelerometers, and other inertial components, as well as specialized sensor testing.
