I used this actuator for a project based on another actuator from another company (Recoil) that has an 8 inch travel and the same 3000N rating had worked great, I needed a 4" actuator and bought it when fitted to the project mentioned earlier, it didn't work even with a little manual help, very frustrating, I have the motor replaced with an 8" recoil actuator (I needed 4 inches of travel) and worked great, money well spent here, if you need less power this might work for you
