linear actuators for hydraulics

[dyel1500]

Does anyone know of some type of linear actuator that can handle a light load (~200lbs force max), with variable stroke (0-6") [increments aren't super important, 1/2" would still be fine], that can actuate and reverse in rapid succession (needs to make full 6" stroke within 1 second) for up to an hour?

Attempting to make a pulsatile hydraulic pump for part testing.

If anyone is aware of where to start the search or knows of suppliers please let me know.

Bonus points if you can find one that operates on 120v.

For a pulsatile hydraulic pump requiring a 6" stroke in 1 second at 200 lbs of force, consider a high-speed linear actuator with a high-duty cycle, a hydraulic cylinder for consistent force and speed, or a servo motor with a crank-slider mechanism for precision. Ensure the solution can handle continuous operation to avoid overheating. Use dynamic control systems to manage rapid actuation cycles, and convert 120V to the required voltage if needed. Focus on mechanisms rated for high speed and repetitive motion for durability and efficiency.

I can suggest you review this product: Linear Actuator
