HGR20 Linear Guide Rail kit 2Pcs HGR20 1500mm Linear Slide Rails and 4Pcs HGH20CA Linear Blocks Bearing Block, Anti Rust and High Precision CNC Parts for Automated Printer

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

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

Far higher quality than I expected!!!

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.

Best conception four my conception

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.

Exactly what I needed, at a great price
