CNCMANS SBR20-1500mm Linear Rail Linear Rails and Bearings Kit 2Pcs SBR20 1500mm Long Fully Supported Shaft Guide with 4Pcs SBR20UU Linear Bearing Slide Block Linear Guide for CNC Equipments

Exceptional Linear Rail Kit, smooth and precise. I used this with a SpecTool Router Sled Kit. These rails precisely fit together with this sled and perform excellently. I'm very impressed with the rollability of these rails. They are smooth and durable. Overall construction is superior and resulted in a very professional router sled for my use. I am more than pleased. I did contact the seller with a couple of questions, and they quickly and accurately responded. It was a very nice experience. Highly recommended! These are an exceptional value for their high build quality and customer support.

Good quality, great buy

Works pretty good so far. Not too hard to align. Fairly smooth.

These did what they claim they do. No issues with these so far, at all. So I ordered more as I have many uses for them.

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

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.

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.

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.
