600mm SBR16 Linear Rail + SBR16UU Slide Bearing Block for Fully Supported Linear Rail 16mm Linear Rail Overall Length 23.6 inch/600mm

Seriously super sturdy combined with the bearings smooth operation made it a breeze to create sliding saw and router.

Worked out great. Built $800 jig for $150. Very smooth come in easy to assemble. If I had a concern it would only be due to dust getting into the bearing surfaces as time goes on. Extremely functional and well built.

We used these for a custom build of a display that needed to be assembled and disassembled after each show. They are hardy duty and worked as expected.

Smooth rails. They were straight and sturdy, very nice weight. The sliders (or whatever they are called) are ball bearing and smooth. Add a thin film of oil and it’s like ice. Used as a router sled build and it did very well in high dust environment. The only problem encountered. Supplied hex head thumbscrews for the slider blocks. Unnecessarily long. It was an issue that I saw on a video but forgot about when I ordered. Can’t remember the length supplied, but too long and I had to make a store run and scrounge the specialty fastener section for anything to work. Had to mix and match items but found a solution. An annoyance that didn’t need to be present, but the when corrected the rails are great.

My seller, GUWANJI, replaced my shipping damage quickly and graciously. Thank you. Their product is fine.
