Linear Guide Rail HGR20-1000mm

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 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.

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

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.

Great Fit. Arrived from China in 10 days. thanks

one bearing block found to be totally stiff and catches when pushed. Stiff enough to not move under its own weight. I have just found this out today, so nothing to it, I'll take it apart when I'll have the time for a deep clean and see how it goes, perhaps things pan out. Apart from that one thing, all things are good. EDIT>>>>>Supplier has contacted me with a solution as soon as he saw my post, and we are working upon an equitable solution. EDIT>>>>>the seller has offered what basically is a refund covering the faulty block, which I accepted. The refund has already arrived at my account. I have nothing but positive vibes for this seller.

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.

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

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.

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