Details
Airtac MGN12H linear rail with one H-type (long) carriage, Z2 preload, in 300 or 350 mm. Z2 is the medium preload: no play in the carriage, but it still rolls freely by hand. That's the grade I'd put on an X axis, where a loose carriage shows up as ringing in your prints and a stiff one costs you acceleration.
On a Voron 2.4 or Trident, 300 mm is the X rail for a 250 build and 350 mm for a 300 build. It is also the carriage size the Monolith X axis uses. Check your BOM for other frames.
Airtac is a proper Taiwanese rail brand rather than a relabelled AliExpress rail: the carriages are matched to the rail and don't need sorting through. I stock them because that's what I'd put in my own printer.
