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.
