Overall met expectations at a low price, however, it did not come with the plum coupling as mentioned in the description. However, the high cost to ship for returns was more than the cost of the coupling
I ended up buying 3 sets of these to build a machine. They are performing perfectly. Would recommend for anyone doing a home project, will update after a year or so to see how they hold up but it looks promising
Updated. The defective rail was replaced and they work great.
Bought 4 sets of different length rails and ball screws for a cnc router build. 7 of the rails were fine but one of the 1000 mm rails was ground .5 mm wider then the other 7 so there is no way to get the bearings on it. Have contacted the seller and will update this review if it is resolved. I am a little confused because the price has now dropped by $50 also and am wondering if it is because of quality issues.Update 9/23 Defective rail was quickly replaced and all my rails are extremely smooth working now. Check out my CNC router build using these assemblies on my YouTube channel Unemployed Redneck Hillbilly Creations. Great seller to deal with.
They came in early and were just as stated.Smooth action from the ball screw and the bearings slid in nice and smooth also.Price is a little high but unlike others these showed up and were packaged very nice.
All components fit well together and linear rails slide without friction or noise. This has a great value for the cost and is helping me to build a CNC router easily.
