Electric Rodless Linear Screw Actuators

Select the Right Linear Actuator: Making Sense of Manufacturer Specifications
In the world of electromechanical linear actuators, a product that has the "highest" output rating, whether it is loads, moments, or thrust can be a distinct competitive advantage. When selecting the proper actuator for an application, the product that has the "highest" rating is often determined to be the superior, robust choice. However, how long the actuator performs is what really counts. How do you compare manufacturer's published specification ratings so you can make a meaningful comparison? It's all about life and load. This paper will give concrete examples that compare specifications and explain how to interpret the results.
