Customer Reviews for VEVOR Linear Guide Rail 2Pcs HGR20-600mm Linear Slide Rail with 1Pcs RM1605-800mm Ballscrew with BF12/BK12 Kit Linear Slide Rail Guide Rail Square for DIY CNC Routers Lathes Mills

Overall a nice product, fists well together. Rails are thick and sturdy, ball screw works well. Satisfied with the purchase.

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.

Not good packaging but, decent item.

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.

Work incredible well. Much better than I had anticipated. I wouldn't expect to spend a lot more on these parts but for the money they work great.

As advertised

Seems fit and finished well. Haven’t installed yet so performance can’t be evaluated but otherwise happy with this purchase

I am very pleased with the product. I was able to connect a stepper motor directly to the the ball screw with the coupling included. The tolerances are extremely tight, but all went together very well. I am impressed with the quality. I only purchase one set incase I was unhappy, however, now will be purchasing more units to finish the project. Well done.

the rails and blocks i got HGR20-1500mm where great for what i paid but the ball screw ball screw-nut, and pillows are a bit small for the length ... there is about .020' runout so trying to get 300ipm of travel probably not going to be happening but if you run them slowish they would be fine.... oh and something that should be mentioned is the ballscrew block that is supposed to have thrust bearing (nearest the motor) just has two regular bearings so there is .005 worth of backlash (in mine) there alone. but really i paid less for the set than i would just for one name brand block so at the end of the day i'm happy ...... thanks
