Theses rails work very well. I am using them vertically and they slide down very easily. However, some of the ball bearings have fallen out of the guides, and the guides are partly plastic, which means they will wear out long before the rails do. By the way, how do you order replacement bearings?

Ho acquistato binari nuovi poi controllando il contenuto del pacco mi rendo conto che i binari erano usati

While I have generally been happy with Vevor products, these two items are of surprisingly low quality and design. First of all, all four items arrived bent. The 1800mm guides were 1/4" (6mm) out f flat, raised in the middle. the 1200 mm ones were likewise bent, but only 3 mm (1/8") out of flat. I was able to to mostly ( but not completely) straighten them by placing them between two sawhorses and applying pressure in the middle, but they are too malleable and have to be attached to a rigid substrate to hold their form. I had to buy some extruded aluminum linear rail at great expense to attach them to in order to make them stiff enough. without this, they will easily deform with just a little pressure. But then I discovered the other design defect. I think it likely that many who buy these intend to use them in sets of four with two attached to the sliders on the other two, in order to make a router sled like I wanted to. The problem is that while the sliders are 48mm wide with a square bolt hole pattern at 35 mm (tapped for 6m-10 bolts), the aluminum support for the linear rods are however only 44mm wide with holes at 30 mm. While it is possible to drill additional holes in the support at 35 mm to match the sliders , drilling hols at 35 mm spacing means that the holes intersect the edge of the support making it nearly impossible to drill them at the correct spacing. this problem could easily have been fixed by making the rod support just 4mm wider. Summary: the rods are not stiff enough, and the aluminum support structure is 4 mm too narrow to attach them easily to the sliders on another set in order to make a router sled. My recommendation: don't buy these if this is your intent or you will be sorry.

Ein Paar Schienen waren perfekt und das andere Paar war leicht windschief. Schade dass ein Umtausch so umständlich und kompliziert sein muss. so habe ich mich halt damit arrangiert und werde in Zukunft meine Ware anderswo kaufen.

Excelent product.But at the time when I placed the order delivery time was 4 days.It took 9 days with 5 interventions at customer service and I heard all kind of excuses.For that problem I asked for a discount on my next purcese but they ignored my request.Product 5 stars and all around service 2 stars.I am dissapointed.

This product is not what I ordered. You sent me extensions for a forklift. I hadn't opened the package until today, when I was going to use it.

Rails arrived bent, contacted customer support for an exchange or refund and they said no.

I give it 1 star and it's not because the product is of poor quality, it is a good product and has good quality. The only problem is that it arrived incomplete. The accessories were 2 SBR20 rails of 2200mm and 4 SBR20UU blocks and only 2 SBR20UU blocks arrived. I have been talking to customer service for a week and they do not want to solve my problem. The customer service is very bad.

Junk. Don't buy Vevor rails. This company does not stand behind their products and it's impossible to get return authorization

Pretty weak
