The rail is a good quality and I've had no issues with it

Exactly as described. Smooth, steady movement.I was even able to fit a different bearing on the MGN12 rail, which doesn't always work because of slight differences in manufacturing.

Great rail to carriage fit... but I ordered 800mm and recieved 750mm.

This unit came straight and working well out of the box. Smooth glide without additional grease. Packaged well!

comes in a sealed packaged oiled to prevent rust. Clean them and re oil with a light lubricant.

No frills, this is just a standard linear rail and guide.I installed on a laser engraver (Bachin) that was rolling on t-track with bearings and had a lot of play in all axis. The linear rails fixed the issue. They move freely upon arrival with only wiping away the protective oil.4-star because one of the two in the pair was missing the rubber end stops (not a major issue in my situation)

These linear bearing blocks seem to be of decent quality. The surfaces are all ground flat and are dimensionally accurate. They were exceptionally tight on the first linear rail i tried to install them and I was certain that something was wrong with the blocks since the block that came with the rail slides smoothly. I was ready to write a bad review but first thought I should try them on another rail to be sure. I am pleased to report that they fit perfectly on the second rail and it seems my original rail perhaps to blame. Lesson learned: double check all the parts before assuming which part is bad.
