Looks well made. The mounting bolts are only approximately 3/4” long they could be too short for mounting on a plate. I purchased 5mm 30 bolts to fasten to 100 wall square steel tube.This product could have been much better packed. More protective wrap would be a good idea.
Very heavy duty, will work perfectly for router copier that I’m making.It would be nice if they had mounting holes drilled in the base, but not a show stopper for me. I can drill my own mounting holes.
Sturdy and better than square Linear Motion Guides
I use this pair suspended holding my Z-axis for my CNC Machine and have no sag or bowing when cutting. It is very smooth in my setup and has very little twist. I found these better than using the rectangle Linear Guides using MGN bearings.
