Customer Reviews for VEVOR Linear Guide Rail, 2PCS HGR20-1000mm Linear Slide Rail + 1Pcs RM1605-1000mm Ballscrew with BF12/BK12 Kit, Coupling, Slide Blocks Linear Guide Rail Set for DIY CNC Routers Lathes Mills

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

minor part missing,,, took a phone call and email pics but part arrived in a few days.terrific service

couldnt ask for more

perfect execution

I ordered these components for a CNC router I am making. I first purchased one to see if it was of acceptable quality, then purchased two more for dual Y axis and single X axis. The packaging was excellent, each piece sealed in a plastic bag and protected from shipping damage. All the parts were there and the fit and finish outstanding. I don't have the equipment to evaluate the tolerances down to the micron level but all the holes lined up and the parts slide as one would expect.The carriages do not move on the rails without some force, primarily due to the rubber wiper on each end of the carriage to protect the ball bearings. With 4X rails and 2X carriages/rail in the Y direction, this means there is a bit of force required to move the entire assembly. I am sure the NEMA 23 stepper motors will easily overcome this force through turning the ball screw but I was surprised at the friction of the seals. That said, the assembly is so rigid that my router seems like it will have incredible precision. We will soon see!

I ordered 3 sets of these rails and ball screws, they arrived sooner than expected and the seller was quick to answer questions. The rails and ball screws are very well made and have tight tolerances. I will buy from them again.

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.

Typical quality (excellent) of these no-name prismatic rail and ballscrew commodity items, but at a price much cheaper than other places. Very satisfied, highly recommended.
