3D Printer Rollers High Speed Gantry Wheels POM Pulley (26pcs/Pack) for Creality Ender 3 CR10 Rollers Artillery Sidewinder x1 Rollers Upgrade

The wheels were great. I had a problem with the first set I received. But it was Amazon that was to blame. The package was opened and missing some of the wheels. The company promptly shipped out a replacement bag, which was sealed and had the correct number of items. I hadn't returned the original before they sent the new ones. And they arrived the day after I began the return process. I highly recommend these wheels. I used mine to replace the defunct original POM wheels on my FOKOOS Odin 5 3D printer. These wheels were of a much higher quality than the FOKOOS wheels that came on the machine.

Used for my JDs garage mini CNC plasma table build, work great.

The bearings are kind of unusual, there's a brass center ring that needs to be coaxed into place so this can be placed on the axle. It helps to use small dab of silicone grease to hold that ring so it doesn't fall back in when trying to install wheel.

Perfect for Longer LK5 pro! I had flat spots which were causing some banding in my prints. This fixed everything right up and feels like an upgrade over what came with my printer. Great value for the money, great appearance and great functionality! Highly recommended!

Replaced old POM wheels on 3d printer with these. So far, no issues after months and months.

These wheels came oiled and ready to run. Used them on 2 printers so far with zero issues.

These have nice bearings in them. Better then the stock ones!

faster then stock, seems quitter too. Not as fast a linear rail but happy with increase vs cost. Print @ 180mm @.4 and 1.0 with no issue. Can print faster but starts squeaking at higher speeds, unless recently tuned/ tightened down. Then done 250mm with slight under extrusion. Also a great way to upgrade and learn how to assemble y and x axis @ the same time.
