Choosing the best linear actuator for a task takes a thorough understanding of the application. The basics like the weight of the load, the distance the load’s to be moved, and the speed and force needed are all important factors. A machine designer may also need to consider variables like environmental conditions, data collection and reporting, as well as flexibility/programmability requirements.
If the application calls for a high force linear actuator, the usual solution has been a hydraulic cylinder. However, high force electric linear actuators are now available (many with roller screws) and offer distinct advantages. Our new infographic compares the performance of electric, hydraulic and servohydraulic actuators on intelligence and operational parameters.
