Customer Reviews for VEVOR Linear Rail SBR20-1200mm 20mm Linear Rail Shaft Rod W/ 4 SBR20UU Blocks

I am very pleased with the quality of the linear rails and smooth operation. The customer service was outstanding. I has some issues with installing the ball nut and the bearings fell out. The company didn't have the nuts locally and had them sent from china at no additional cost. They provided updates to let me know about delay because of the extended holiday.

Awesome product! I was able to finish my laser machine and worked perfectly.Some of the blocks are loose but all you need to do is use the screws on the side to adjust them.

They seem like good quality out of the box! Time will tell if the mechanisms hold up!

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.
