Servo indexing tables have a constant lead cam with a servo motor drive for programmable motion. The tables provide fast, accurate motion with the ability to move medium to heavy loads. The preloaded cam and turret eliminate backlash. The RU Series servo indexing table is available in 11 sizes. The tables come with varying ratios to maximize the motor’s torque capacity, speed requirements and accuracy. Special applications may require double reduction ratio of the internal cam and an additional reducer to provide large torque capacities or slower speed.
