ED/ECO SERIES

 

Sankyo America Inc. introduces the ED/Eco-Series

Sankyo America's new ECO series is designed to be an economical and ecological conscious index drive, while surpassing all the valuable features from current product range. While the ECO series continues to provide high-speed performance, reliability, and rigid structure, it also achieves a clean and easy interface.

In detail, the machined housing is nickel-plated to offer an extremely flat and smooth surface. The output shaft is a flange with integrated shaft with many accessories, such as a table or sprocket, can be easily mounted on. The grease lubrication gives the ECO series maintenance free operation. Furthermore, the revised design allows Sankyo America to offer the Eco series at significant cost savings.

In order to meet today's design requirements, peripheral equipment is also available for the ECO series. Optional equipment includes torque limiters for overload protection, worm gear reducers for a reliable input drive, and cam balancers to eliminate vibration due to unstable input rotation.

Features

•Center distance of 45, 60, 70, 80, or 110 mm are standard.
•Number of stops - 2, 3, 4, 6, 8, or 12 are standard.
•Sankyo America's original SMS-3 cam curve comes standard for better dynamic characteristics.
•Flange type output with integrated shaft for easy use.
•Maintenance-free grease lubrication.
•Torque limiter on output shaft, geared motor on input shaft, timing cam, and sensors are immediately available options.
•A worm gear reducer input drive and/or cam balancers are available as specially designed options.
