ACTUATORS
EDrive actuators are designed, manufactured, tested, and serviced in West Hartford, CT. Founded in 1980, EDrive Design, Inc. initially developed a wide variety of heavy duty ball screw linear actuators, targeting the machine tool retrofit market. Thus, we established our guiding principles of conservative design, rugged construction, long life, and high precision.
EDrive manufactures electro-mechanical linear servo actuators that replace hydraulic cylinders for motion control applications. EDrive has shown consistent success in the toughest applications, e.g. high loads, high speeds, high precision, and extreme durability. Precision ball screw systems, tailored for maximum life, load and speed, provide the motion while fully enclosed, thus eliminating contamination related failures.
A "standardized" product line facilitates ready availability; however, modified designs in the interest of easing the customers' utilization of our products is done willingly. EDrive is focused on understanding the application, recommending the optimum solution, and making it easier for the customer to mechanically and electrically interface with their existing equipment. EDrive continues to expand the capabilities of its products; with the most recent addition of the HDL™ offering an internal load cell for precise control of force as well as position and motion.
After market service also remains a high priority. Emergency repairs are routinely performed within one day. If the required ballscrew is not in stock, a typical rebuild is 4-5 days.
