QWORK Small V-Wheel Plate, 2 Pack V-Slot Gantry Rod Plate with Wheel, for 2020 Aluminum Profile, CNC and 3D Printer Parts Black Wheel

These work well. This is a revised review. First review of 1 star never showed up. I was going to edit it, but can't edit if it doesn't show up. They didn't fit. However I didn't know these are adjustable. If you slightly loosen the wheels, the hex spacer holes are off center. You can turn the hex, made for a wrench, and adjust the cam that is built in and vary the wheel spacing closer or further apart to make them fit. It would be nice if this was in the description of the product.

I haven't used these yet but they appear to be very well made. The anodizing on the aluminum plate is particularly good quality. I've used basically identical gantry plates from OpenBuilds and these are just a nice. Two things to know, because there seems to be some confusion in the comment section: 1. These are intended for use with V-Slot extrusions, NOT plain old extrusions. The wheels are beveled and ride on the beveled edges of the V-Slot. If you try to use it on plain extrusions It will likely be impossible to fit. 2. Two of the wheels have hex-shaped spacers that are used to adjust a cam mechanism to adjust tension. You loosen the screws that hold the wheels on and then rotate the spacer to move the wheel in and out until you take up any play and get the tension where you want it - then tighten the screws back down. There are YouTube videos with instructions.

Items as described. Fast delivery. Thanks.

I gave a poor review earlier but after further investigation I have to note and caution everyone that the extruded aluminum was the issue causing the misalignment. I tested the part on a different 2020 piece from a different supplier and had no alignment problems at all. PROCEED WITH CAUTION but the plates themselves seem to be ok after all.

Used these to make custom drawer slides for my workshop. Worked great. Two of the wheels are on an offset cam nut so you can adjust how tight they are You can’t use regular 2020 T slot. It has to specifically be “v-slot”
