Customer Reviews for Sbr20-2200mm 2x Linear Rail Set 4x Bearing Block 20mm Grinding Shaft Rod

The guide blocks for the two sets of rails are different sizes with different hole patterns. Also, the blocks for the 1200mm rails have through holes while the blocks on the 2200mm rails are not drilled all the way through. I can see no reason for the blocks to be different. This made measuring and drilling the acrylic pieces that came with the 2200mm rail much more difficult. In contrast the through holes on the 1200mm rail blocks made it very easy to mark and drill out the acrylic router plate. Please consider using the same through drilled blocks for ALL your guide rails and your future customers should be much happier with their purchases. You might also consider selling acrylic pieces that are designed to connect the guide blocks on the 2200mm guide to the end stops on the cross rails. Having the acrylic pieces all pre drilled would make assembly much easier. Thank you, Bob McRae Bob.mcrae@gmail.com

Bought these (2200mm and 1000mm) to make a router sled for flattening a large desktop I'm making. They worked great; looking forward to having another opportunity to use them. One minor issue was that one of the slider dropped some ball bearing during shipment, but Vevor took care of it right away.

Good product. But dissapinted. Writes like new. But received as used.

The rails are wonderful and work as described. Quality piece. Would have been nice if screws were available as I had to go to hardware store and purchase screws. Also, I would have liked is if the Router Plate was made available, a plate with drilled out holes that match up with the rail slides. If I missed something, please respond back with a part number for the plate....if none available then I will have to make one.......would prefer one that is already made with perfectly aligned screw holes already made. Other than that, good quality and quick shipping...

I see a lot of reviews on these sub level 4. Folks your getting \"good accuracy\" for a VERY CHEAP price. If you want betting quality, guess what, it costs major bucks! To Daniel with the router sled, you installed them upside down. The axial load is at its least support the way you have it. I suggest buying the 20mm full bearing SBR20 Linear Slide Rails instead. These are VERY good quality for the price.

Good bearings, made a router sled rolls easily and smoothly on the rails. Bearing blocks use four 6mm screws. I lasered a mounting plate from 1/4" acrylic to mount the Vevo rails.

I have purchased several items from Vevor and have never been disappointed This is my second order and all items work great Thanks Vevor for the fast shipping and excellent products

These have worked great for my router sled I built to flatten slabs. I am soon going to be purchasing more for another project!

For two rods four bearings and four clams you really can't complain I spent less than $100 on 2 sets of 20mm x 1200mm but 4 bearings are a bit sloppy 2 are perfect and 2 are way to tight

Item was delivered on time. These rails are heavy and the box they were delivered in was thin, cheap, and very damaged. The rails arrived with missing parts. Guessing the parts fell out of the holes in the box somewhere down the line. I initiated a replacement and it came as expected. Rails work as expected.
