Sankyo servo indexing tables offer a constant lead cam with a servo motor drive for programmable motion. Our servo indexing tables provide fast, highly accurate motion, with the added capability to move medium to heavy loads. Our preloaded cam & turret provides a zero-backlash servo indexing table for all your automation needs. The RU Series servo indexing table is available in 11 different sizes. These servo indexing tables come with varying ratios to maximize the motor’s torque capacity and speed requirements while enhancing the overall accuracy. Special applications may require double reduction ratio of the internal cam and an additional reducer to provide large torque capacities or slower speed.
