Customer Reviews for Sbr16-1000mm 2 X Linear Rail 4 X Bearing Blocks Cnc Router Bearing Sbr 16uu

Great product: Smooth and precise operation, sturdy. Used the product to create a sliding sofa/bed on an RV. Be Aware: If you are planing on extending the length of the slider by joining two butt ends together, the tolerances on the ball bearings slider are so tight that it is difficult to line them up and pass the bearings through. Otherwise, that is a testament to their precision.

I needed a way to flatten a very large end grain cutting board. They worked great as the support rails for a router sled. Easy to take down too.

Fast shipment. Well satisfied

These rails are not perfect but they are really good. Vevor had the cheapest price and free shipping so I was worried these might look like they were built by monkeys. Instead the smooth steel rods were clean, smooth strong and defect free. Lightly oiled and wrapped in plastic and foam to prevent rust or damage. The rollers are exactly what you would expect. An Aluminum cast piece that has been tapped for threads with a bearing added into the middle. They roll a little rough until you put a load on them then they quiet down and ride smooth. Don't want to oil them as it will mix with saw dust in my shop. The aluminum feet to the rods are probably the worst part of them. They are straight and flat but the mounting holes were drilled by hand. So they are not precisely located, spaced or even sized. Not a problem for me. So I will give it a 5 star as the price fits.

Made a router sled with these to flatten large planks, works great. Strong and straight.

Just wish they made longer ones.

Exactly what I wanted but I couldn't find where to order more of the blocks

Great quality love them they worked perfect

Excellent above standards

The rails were perfect for my router sled application. I will buy from Vevor again when the need arises.
