This item is an excellent product and at a very competative price when compared to other sellers. I would certainly purchase this or similar item again.

These were just right to build my router sled. very smooth rollers and glides really well. would purchase again

I ordered these rails as a replacement setup for my home made panel saw. They arrived in good condition with all of the parts. The pillow blocks fit perfectly and run along the rail smoothly. They aren_ as smooth as high end blocks, but you can_ beat the price.

Great for the router sled project I'm working on.

I have used these to build a router ‘flattening sled’ - Really well made rails and bearings for this price. Delivery was on time, so all in all really very pleased. A nice touch would have been to provide bolts / screws to attach the bearing runners to “whatever your attaching” to them. That said I would highly recommend these, thank you Vevor.

I built a cnc desk top machine several years ago and used simular parts but about half the size and even with importing the parts directly from China it cost me well over 3 times the price I had checked the price of parts in uk but they would have cost a lot more than I could afford, this set has all of the mechanical parts you would need to build your own cnc cutter/engraver except for the base which could be any type of stiff board like a piece of kitchen worktop, I am going to use a workbench which I bought from amazon :- https://www.amazon.co.uk/dp/B0CNGHX25M?psc=1&ref=ppx_yo2ov_dt_b_product_details As it is a great heavy duty workbench which has adjustable legs which allow 3 different heights so you can use it sat down or stood up I have 2 of them which I use with the wheels fitted and if you want to move it it is very easy to move and it you want it not to it has brakes on the wheels and doesn't move at all. The only other thing it will need is stepper motors plus drivers, a program controller, and power supply's which will require 48 volts for the stepper motors and a 12 volt supply for the program controller and limit switches. I will add photos once built.

I wasn't expecting much for this price but was surprised at the accuracy. Still need to do some tests for backlash in the lead screws but as yet they're absolutely solid. Guide rails aren't the best but perfectly adequate for my use and a little tweaking mops up the slop. Very happy with these.
