Customer Reviews for VEVOR Linear Guide Rail 2Pcs HGR20-1700mm Linear Slide Rail with 1Pcs RM1605-1700mm Ballscrew with BF12/BK12 Kit Linear Slide Rail Guide Rail Square For DIY CNC Routers Lathes Mills

This kit has very smooth motion with minimal resistance.The tolerances are surprisingly tight for the price. I_l definitely use them again for making custom saw stops.

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

Very rigid and works well! The rails don_ slide super easily but that_ probably just preload on the rails. I had no issues aligning them and had no issues with binding. Great for the price!

Good quality and a great value

We_l definitely be ordering more. Great quality for the price

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!

Smoth bearings, perfect fit. No complaints, exactly as advertised

The product has a good value, however it didn_ come with those little green Plugs to cover the Bolt holes. I cannot find anywhere to order them. Without them I_ afraid the wood chips will fall into the Bolt holes and jam the glide blocks.

Seems like good quality.

Excellent quality! Superior delivery.
