The rotational moment acting on the horizontal cursor 34 is canceled out by the attractive force between the magnets 30 and 46 and the repulsive force between the magnets 28 and 44, and the guide rollers 40 and 42 receive almost no pressure from the rail surface. I didn't receive it, and the safety code was 36, 38.
completely floats above the rail surfaces 24 and 26.
