The bearings and rails are the correct size, they were the ones that came with the machine, since this post I did get an upgrade for the X axis

Only to find the rails were too short, but I fixed it by getting some stainless steel spacers M5/5mm/12mm

This has resulted in less flex in the axis and less play but there is still a bit there, I will carry on experimenting.
