    Hello all,

    i have a diy setup with 45 mm aluminium profiles with 2 snc5 150 behind the seat.

    i am planning a rear traction loss. I have 2 questions

    did anybody tried a traction loss with bearing in front and in the back . i was wonderng if the effect would be good

    is a snc5 50 mm stroke enough . I have access to a snc5 50 mm . i was wondering if that is enough


    thanks

    I have traction loss fitted to my sim which has a total movement of 320mm (DC motor chain driven). Only configured in Simtools to use 50% of this which I think feels OK. If you have a 50mm actuator handy then there is no harm in trying it. My traction loss table has a large bearing at the front, with the rest of the table being supported by six wheels. If you are moving both the front and rear (like my surge table) then it would be a sway table and not traction loss (although, if traction loss is not available I will connect it to sway and it still adds to the experience).

    hello thanks for the answer

    i was maybe overthinking it. but what if there is a pivot int the front . + bearing in front and back .
    there will be a slight "sway" but still a rotational motion (rear traction loss). In reallity there is a rear traction + aslight sway...

    i am not sure how sinxperience do though. I have the feeling it is something like that as i was overthinking this think before jumping in buying aluminum

    the only think i have to redo the front as i used 30 mm aluminium (the rear is made of 45 mm aluminium). The 30 mm would flex with that kin of motion

    i was thinking mdf or thick alu plate at the base to avoid flexing or change to 45 mm alu . but it costly

    Ok I think I understand what you want to do (although a simple diagram may help). You should not need another bearing in the back as your seat mover can do this type of motion. Mine is all made out of steel - advantage of using DC motors and chain drive.
