    Hi sn4il,

    In a previous thread that was intended to help people avoid actuator damage, but resulted in an unfortunate competitor hi-jacking, you asked a very important question.

    The answer is, there are no known cases of SCN5 150mm actuator failure.

    Thats good news for me, as i want to buy a pair from you in the near future. (oh and my rig was not fine...;))

    In one of Your thread about broken pin some1 made statement that SCN5 depends only on motor bearings. Is the motor different between 100 and 150 actuators or its just a ball screw?

    I really appreciate what You are doing for the community and I'm looking forward to start with Your dimmensions listed in other thread.
    Personally I think these angles are critical expecially with heavier drivers like myself.
    I was going to use double SCN5's per side but it's more complicated than I thought.

    Hi
    All scn5 are the same
    The screw is allsow guided by the nut.
    Longer strokes are slower because critical speed from screwshaft
    regards

    I agree. The internals are the same, just a longer stroke. However, Dyadic claims that both 100mm and 150mm are capable of 400mm / sec. My guess is that they arer actually capable of slightly more than this at lower stroke lengths. In most implementation, less than 300 mm/sec is all that is achievable anyway due to the load.

    Hi Bernard
    Youre right, there is a standard of 20% safety marge in industry.
    A 150mm is able to reach 480mm/sec before they start vibrate,and a 100mm can have more.
    But there is allso friction from nut and screw thats limiting the rpm.
    Regards
