HYBRID LINEAR ACTUATORS VS. ELECTROMECHANICAL ACTUATORS FOR LONG-STROKE APPLICATIONS

How do Hybrid Linear Actuators compare to electromechanical screw-type actuators in long-stroke applications? In this Ask the Experts video, the experts at Kyntronics demonstrate a 72-inch stroke SHA Hybrid Linear Actuator to explain how hybrid actuator technology approaches long-stroke applications differently than traditional ball screw or roller screw electromechanical actuators.

Key Takeaways:

• No internal mechanical screw or gears: The SHA uses an integral hydraulic cylinder with minimal fluid instead of the internal mechanical screw and gears found in traditional electromechanical actuators.
• Simplified long-stroke sizing: Increasing the stroke length in hybrid actuators do not require a larger pump or servo motor simply because the actuator stroke is longer.
• Different long-stroke design considerations: As stroke length increases, screw-type EMAs require consideration of screw sizing, L10 life calculations, and other mechanical factors that can add complexity and higher costs.
