It works and appears to be good quality They want a 100 characters or more? What do they expect for nothing

The product seems sturdy and straight. However, I am not able to use it because 1 of theSBR20UU Square Type Carriage Bearing Blocks won't fit on the rails.

I just had these delivered for a fold down table project I'm working on. I need something that is quiet but also had good weight capacity. There isn't a great amount of information in the product description so I went to the manufacture site. FYI - Each slide block can handle a static load of 308 lbs and a dynamic load of 198 lbs. I believe the bar itself can handle much more so using two blocks per bar should easily handle 400 lbs.

Decided to make my own router sled and saw some ideas using linear rails. Got 2 sets and had to cut one set to length. Heavy, sturdy and did the job nicely.

Will use these on a sliding table for my tablesaw. Feel sturdy, not quite as smooth as I would like hence the 4 stars. Should work well for what I have in mind though.

These rails took nearly 4 weeks to get to me, which is way too long. Not impressed.!!!!!!!!!!!!!!!!

I added this to a sliding table top that was sliding on dovetail slides, not smooth and wobbly. Now with this the table slides on two solid steel rods and ball bearings. Not totally smooth but exactly what I expected for the price. I'm happy. The shipping was super fast too.

Got what I paid for and what I expected. They were not straight right out of the box, but loosening and then re-tightening the mounting bolts helped straighten them enough for my small hobby diy CNC.

The rails were nice and straight, no bowing, and the SS tracks are well polished. The linear bearings need some adjustment to get them to run relatively smooth. Even after adjustment, the bearings seem rough until you put a load on them after which they run nice and smooth.These work well for my purpose (linear guide rails), but I would hesitate to use them for high precision or low load applications (CNC, printing) simply due to the way the bearings behave without a load.

Good item, however there is not template for the sliders that is not easy to align.
