Linear Guide HGR15 400mm Linear Guide Rail Set, Includes 2Pcs HGR15 Linear Rails and 4Pcs HGR15CA Sliding Block High Precision CNC Parts for Automated Machines

I have ordered two sets of these and they work great and are of good quality. I wouldn't hesitate to order these again.

Great Fit. Arrived from China in 10 days. thanks

I put these under my chair in my office. I use a living room type recliner at my desk, so it allows the chair to move. Of course, it called for a bit of fabication to mount them. This is my 2nd set of these, did the same to my wife's chair.

The bearings are pretty loud even when lubricated. Mounting was easy. Each guide rail on the 1000mm has 15 screw holes so 30 in total but you only get 15 screws. The threaded hole for grease fitting is plastic so easy to cross thread if not careful. Not a bad item for the price.

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.

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.

El producto se ve a simple vista de buena cualidad, pero el vendedor solo envio 16 tornillos , y estos rieles requieren como 46 cada uno, ahora me tocara comprarlos aparte.

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