Sankyo Automation Zero-backlash servo rotary indexing tables
The Sankyo Automation RollerDrive reducer is a precision gear reducer that uses a zero-backlash roller gear mechanism. The unit is constructed from an input shaft and a turret (output shaft) that is assembled with roller followers. The roller followers are preloaded against a screw-like input shaft to eliminate backlash. The RU series servo indexing tables offer a constant lead cam with a servo motor drive for programmable motion. They provide fast and accurate motion and move medium to heavy loads. Available in 11 sizes, the tables come with varying ratios to maximize the motor’s torque capacity and speed requirements.
