    Hi all,

    I am looking for a linear actuator with the below specs:

    -24Vdc
    -Approx. 350kg of force
    -50% to 100% duty cycle

    Does anyone know from where I can buy an actuator with these specs? I found similar products but the duty cycle was 25%, which is not good for my project.

    Any help would be appreciated.

    You could try looking for some more powerful one. I think that if you would run an actuator rated 50% duty cycle at half the maximum load it should be able to work continuously. But better ask the manufacturer first.

    Thanks for the fast reply.

    Actually 50% is ok for me. My problem is finding one which have that duty cycle and is not very expensive :)

    What length of stroke is needed?

    My idea won't work. Missed the 350kg. What are you lifting that weighs 771 Lbs? That's in the industrial range.

    To fully understand your request, could you please explain those duty cycle values?

    Hi again,

    Thanks for your replies. I am going to use the actuator for an industrial robotic arm application, which will by my collage end of year project.

    @ atferrari , thats not -50%. The munus is used as a bullet. I want the duty cycle not to be less than 50% since the arm will be used repetitively. Preferably, the duty cycle will be 100%, but an actuator with that cycle would be very expensive.

    Any help will be appreciated. Thanks.

    OK. Now it makes sense.

    Sorry, I am used to those from Firgelli (Canada).

    Buena suerte!

    For that size of actuator I'd go for a pneumatic ram (if you have access to compressed air) or a servo with a leadscrew/ballscrew.

    If you wanted to get fancy you could use a linear motor like this:
