SBR20-800mm Linear Rail Linear Rails and Bearings Kit 2Pcs SBR20 800mm Long Fully Supported Shaft Guide with 4Pcs SBR20UU Linear Bearing Slide Block Linear Guide for CNC Equipments

Saved myself thousands using these rails to build a router sled. Great ball bearing action, heavy stainless rails, solid. Great choice for any heavy-duty slide applications.

Slides very smooth and works perfectly.

RAILS ARE STRAIGH AND RIDGED .bEARINGS COULD BE SMOOTHER

packaged good. real good lol. box was a bit banged up from the mail people. but the rails where protected inside the box thank god. they or great rails i am very happy. thank you. would buy again.

These worked great for my project!

Product was fine, but I am missing the end alignment dowels which wasn’t a big deal because I am not in a rush. Reached out to the manufacturer for resolution with no response. When you purchase anything a big part of quality is support. That’s why they received one star.

Great rails. The bearing blocks though have a slight gap between the rail pole and the sides of the bearing block. This allows a back and forth wiggle while the block is on the rail. I’m using these for an application where I don’t want any wiggle room between the bearing block and the rail. Anyone come up with a solution to keep the block fixed on the rail?Thanks

very hefty rails no bending under the weight of a plunge router and my weight reaching over the work piece. they a bit noisy and probably could use more grease but that would cause too much dust buildup. came with hardware screws and a stopper handle but still had to purchase more since they were to long for my application. as a side note i accidentally purchased the wrong size and were too short to complete the task but worked as advertised. very satisfied with this prodcut.
