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

I got this to make a flush cutting jig for my hand router. I was able to cover a cutting board 18"x20" and level both sides in less then 20 minuets. This made the best jig I could ask for it slids very smooth in both directions. I was able to level both sides that I used to take hours tring to level by hand sanding. The Sbr-16 bearing blocks work perfect but they are a little tricky getting them to slide on the rail the first time. I hand 2 that just did not want to go on and I hit them on and some bearings poped out. I was able to snap them back in place and aline the block again on the rails. Its a learing experience for me making this jig with these rails but no regrets. I even ordered me 4 spare bearing blocks. to make more jigs to run on these rails.

I bought 2 different sets of these. For making a router sled and they don't come with screws. So I had fun trying to find the correct size and there aluminum so easily stripped out. It it were not for them not coming with the bolts for the slide blocks I would recommend .

Used to upgrade a DIY wood CNC router. So far they seem like they will work well.

So my intial order was wrong and was missing pieces. Had to return it and got a new one. After receiving it I was able to build my linear rail router sled. It was smooth and easy to assembly. Great overall product

I have bought these with the idea of making a sliding shelf on our bed so that on remote days and sick days my wife can do her work from her laptop in the bed and when not in use the shelf can slide to the foot of the bed out of the wayI have installed the rails and they work great I will be build the shelf and attaching it next weekend

Works fine

Turned these into a DIY slab flattening sled at a 10th of the cost with the same results as a purpose built product at the wood store.

Linear movement can get expensive. These were perfect for my current project.

Just received it and one of the roller blocks is binding up. Took it off the rail and cleaned out the metal flakes. Didn't make any difference.

WAY better then I could have imagined... holly crap... this was designed and built for way more then my home project :) but I could not be happier...
