Customer Reviews for VEVOR Linear Guide Rail Set, SBR16 1000mm, 2 PCS 39.4 in/1000 mm SBR16 Guide Rails and 4 PCS SBR16UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

The bearing blocks moved smooth and were rigid.I pushed the bearing blocks onto the rails easily.Very good quality for very low price.

Exactly what I needed for a great price

Items were received, measured for length, one was cut down to the exact measurement of 2000 mm; installed the next day.One of the SBR16UU Bearing Blocks, failed the 5mm hole thread requirement. I am going to oversize the thread to a 6 mm with "Tap and Die" set later. I am keeping it for a spare asset.Another SBR16UU Bearing Block had "frozen" rolls bearings (balls); however, I planned ahead after reading previous reviews. I ordered and received four spare SBR16UU Bearing Blocks. Minor delay in getting it running but the previous reviews were very helpful.

Solid and firm, excellent quality, met all my expectations

Used for personal project and fit application well

Great product, just as expected.

I used this product for a slab flattening jig with my router. Even with a very dusty environment, the bearing slides easily, maybe even too easily as I went off the end of the rails once, but that is really my bad. I wish that there were female threads at the end of the rails inline with the rail axis to facilitate adding a stop to prevent going off the end. When it went off the end, a single ball bearing did dislodged and was lost, but that still didn't prevent it from moving smoothly on the rails even after that.

Smooth sliders, using for router sled

excellent manufacturing, mounting blocks glide effortlessly.

They are very straight. Under load very smooth I will update when they are running
