Disappointed with the quality and consistency of these linear rails and carriages. One rail and carriage was nice and glided smoothly. The other two carriages were rough, with one halting very significantly throughout its travel. The second rail was also rough, with signs of use, and a ding/pit that I had to smooth out with fine sandpaper. I disassembled and cleaned the carriages, and found that the number of ball bearings in the races was inconsistent between them as well. I may consider buying new ceramic bearings at some point and try upgrading these, but for now they'll have to do as they are.

I used these to convert my Ender 3 V3 KE from the standard set up to a linear rail for the Y access motion. The rail came neatly packaged and had no defects, rust, and happily both were straight with no warps.I lubed up the bearings and installed with no issue.

The first order has the wrong size and count but that's Amazon's fault. The replacement rails are smooth and very stiff. Would buy again.

Received dud and reached out to the seller and they contacted me after almost 1.5 weeks. I ended returning it.

Bought these to convert my Ender 5 Plus 3D printer to linear rails and so far, so good. No issues, nice and straight, rigid, rolls nice and smooth.

The rails work well on my ender 6 conversion. They make the printer a little faster to print with and just add a sleekness.

I have mixed feelings about these rails. on one hand they are nice and tight, they really is no slop or play in them at all. the problem is they don't slide smoothly, there are spots where they seem to bind and stick a bit. you have to take them apart, soak them in rubbing alcohol, clean all the ball bearings and the tracks they ride in, apply a little grease and put them back together (without losing any ball bearings). if your willing to do that then I guess I would recommend them. If you don't want to do the cleaning then get the Hiwin rails.

Works well for 3D printer. Would buy again. Did require removal of existing grease and re-greasing.

So far, of all the brands I've tried, these are the only ones that have consistently moved on their own after cleaning and lubrication.

Even out of the box before cleaning them and lubing, they move so smooth and have no fine bumps or anything, they also did not come with any factory packing junk all over them and are properly packaged. I have to say they are really worth the money. I have bought loads of other brands and now will stick with this brand no questions asked. I also only bought the 250mm because I need some carriages and for the price it was worth getting the whole thing and wow.PLEASE keep building them like this and keep that kind of quality control.

The bearing balls in the sliders needed a little cleaning and lube but the quality was there for what I paid. The rails are machines nice and it was packaged in a way that keeps everything stationary so you don’t have it come apart in transit and lose bearing balls. The balls were intact people!! Lmao. I got these to add linear rails to my CR-10 V3 and will be buying more the do the X and Z axis later on.

These are much better than I expected and move very smoothly with very low force. The rubber stoppers at the ends are a nice feature that keeps the carriage from falling off while assembling things.
