The authors propose a flexible shaft actuator whose slider has high-speed and long-stroke motion capability. However, the rolling resistance of rollers in the slider must be investigated to improve the motion performance. In this study, we identify the rolling resistance and optimize the roller design. First, possible factors causing rolling resistance are investigated. We found that the elastic hysteresis loss was the main factor to approximate the resistance. Finally, we optimized the roller radius using the experimental results.
