IverntechMGN12 300mm 400mm 450mm 700mm Linear Rail Guide with MGN12H Carriage Block for 3D Printer and CNC Parts MGN12H Linear Guide AW014 1

Q: How hard is it to trim these down? I need a length of 440 mm and would probably be getting a 450 and trimming 5 mm off each end. what tool would be

An angle head grinder and thin abrasive wheel will go through it just fine. Dip it in water if it gets too hot. Completely tape the carriage to keep out dust. (Don’t take it off.)

Q: What size t nuts do you use

Hi, M3 t nuts and hex screws are suitable

Q: Are the holes in the carriage threaded?

The holes in the carriage are tapped 3MM. The rail holes are drilled and counterbored for 3MM sockethead cap screws.

Q: Are these bearing blocks pre-loaded?

Yes. Only thing i recommend doing is to clean well (i used a automotive part cleaner spray solvent) and lubricate properly when you get them. Mine are still performing flawlessly.
