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

Product was as billed. Would order again from this vendor.

This is a awesome product! I was able to finish my laser machine . Some people say that the blocks are too loose, some are but they have adjustable screws to make them the right tension.

havnt use them yet but semes like thay are good

This was very helpful in my project. Used it to build a guide rail system for a cnc machine. Worked wonderfully!

48 inches, straight, no binding. Bearing blocks have smooth motion. Glad i bought 3 sets. No trouble with any of them. 4 stars because i have never rated anything 5 out of 5. These are beefy and worth the price to me.

Great deal

diy router copy machine. excellent base to start with.

These are the Y axis rails for a 48 X 96 inch CNC Mill I'm building. I bought 4 rails took two rails, removed them from the base shifted the base by two holes and remounted it then I have two sets of 8 foot rails. and the bearings slide right across the TINY gap as if it were not there

I bought these rails to fabricate a custom TV mount for a VERY large flatscreen we bought. I wanted to be able to slide the tv to the side to be able to access a hidden area behind the tv where the receiver, etc would be stored. The tv weighs in at 97 lbs, and I am able to slide it back and forth on these with a light touch of only 1 finger. They seem to be well constructed and are well worth the price.

worth getting more at the price I paid.
