What more can you say if they are both smooth as silk and precision to the Tee. Price isn't too bad either!

Achtung: die m6 schrauben für die schlitten sind an nicht im Lieferumfang enthalten, warum auch immer!! Das hat mich sehr gestört… 1 von 3 schlitten hat reichlich spiel und rattert, hatte noch welche über und konnte den austauschen… nun läuft alles, wer aber keine m6 schrauben und mindestens einen ersatzschlitten rumliegen hat, sollte eine alternative suchen!!

I took a gamble and bought the cheapest rails amazon had to offer (these) and they turned out better than expected. Very straight, and only one wobbly carriage, which I expected and had already bought quality bearings and spare carriages in case there was a lemon or 4. No perceptible play in the other 3 carriages, for this price point The value is insane. Dont let those gatekeepers on cnc forums tell you you have to drop 500 on name brand rails! Just be ready to send back for replacements if they don't test out well.

Package arrived damaged. Glide blocks were missing. When I informed company they suggested I buy them again and they would reimburse. Slides have a large crown in them, which might straighten out when bolted down. Nonsense upon garbage. Be warned.

I ordered these rails as a replacement setup for my home made panel saw. They arrived in good condition with all of the parts. The pillow blocks fit perfectly and run along the rail smoothly. They aren’t as smooth as high end blocks, but you can’t beat the price.

These linear rails came well packed and shipping was fast. They appear well made and heavy duty. These are the second set I have gotten and would buy them again. The surface hardening is really tough. If they must be cut forget the hacksaw they need to be cut with an abrasive wheel. A dremmel will do the job. It took 2 discs to get through it.
