Yikes! That's an awful lot of fast motion, assuming your average stroke of 12". A lead screw wouldn't last long (months, not years). Better use loctite on those fasteners, or it'll shake itself apart.

Oh, and doing the math, that's about 3 meters per second at 12" and 300 cycles per minute, assuming no time for acceleration and deceleration.

To put it into perspective, that's as fast as a commercial paint can shaker, faster than the average person would shake a spray paint can. And to move <1 kg at that rate is pretty demanding, mechanically.

I think you need to carefully re-think whatever you're trying to accomplish, because your design specs are somewhat harsh.
