I wouldn't even use a rotating nut over 2mtr, simply use 20mm pitch with a 2:1 ratio which brings it back in line with 10mm speeds and resolution but halfs the screw speed.

But to answer your question then yes it would be ok over 2mtr. . . . . Now my question to you is why are you wanting rotating nuts with only 2mtr travel.?
