Electric roller screw linear actuator
4 000 - 25 000 lbs, 14 - 20 in/s | Eliminator HDR™ EDRIVE Design

The Eliminator HDR™ is the only roller screw linear actuator manufactured in North America with machine tool grade, heavy wall steel construction.

The Heavy Duty Roller Screw linear actuator series was developed to provide a strong, durable, and precise linear actuator for high end applications. It offers the many advantages of our Ball Screw actuators with additional benefits for certain critical applications such as impact loading. As an alternative to hydraulic actuators, it eliminates many of the associated concerns, such as noise, heat, leakage, controllability, and low stiffness,while handling high loads at high speeds and maintaining the rugged and durable steel construction typical of hydraulics.

E*DRIVE has shown consistent success in the toughest applications, e.g. High loads, high extreme durability. Precision roller screw systems, tailored for maximum life, high impact tolerance, high load and speed, provide precise motion while fully enclosed, thus eliminating contamination related failures. A long bronze nose bearing provides support for the extended piston. Rugged bronze keys in opposing steel slots provide anti-rotation and counter the tangential forces created during high speed,high frequency, and high load operation.

While other actuator designs force a particular motor decision, the HDR is designed to suit virtually any motor, gear box, or gear-head the customer chooses to use.
