HGR20 Linear Guide Rail kit 2Pcs HGR20 2000mm Linear Rail Linear Slide Rails and 4Pcs HGH20CA Linear Blocks Bearing Block, Anti Rust and High Precision CNC Parts for Automated Printer

I bought these rails but when they arrived they were a bit larger than I expected and planned on returning them. These are HGH carriages and not the MGN type so they are much more robust. I am not going to return them and hold on to them for a future project. They are smooth and robust.

These rails were packaged OK but, I would rather have had them packaged in stiff cardboard tubing. As far as quality, these rails and rail blocks are of high quality. Everything was packed in plastic bags and completely oiled for protection. The rail blocks are separate and with a special ball retainers for easy installation. The blocks run smoothly on the rails and have no noise and no play at all. I like the fact that there are two blocks per rail. Excellent job. 5 stars.

So far they look good, have not installed them yet. They feel alittle tight but this is the first time I've used this style of linear rails. I need to know where I can get the plastic bearing retainers so I can take the bearing blocks off the rails without loosing the bearings.

I needed these to fix a machine! Arrived in good condition!

Far higher quality than I expected!!!

bearings all came out when i went to put on now im one slider down :(

On one rail the resistance with all blocks is amazingly horrible. The other rail seems to have been milled to work with the blocks as they will slide without much resistance. Maybe I missed it, is the rail meant to be a project of it's own? Carefully remove material and hone it down so the blocks will function? Some instructions would have been nice in that regard.

Lo instale y funciona perfecto, llevo 1 mes sin problemas.

Best conception four my conception

Exactly what I needed, at a great price

I've installed these on my custom cnc machine, and they work pretty good. The one issue I have is when sliding the connectors onto the rails you need to be very careful or bearings fall out (which you can put back in). Also some seem smoother than others for some reason.
