Creality 3D Printer POM Wheel Plastic Pulley Linear Bearing for Ender 3/Ender 3 ProEnder 3 V2,CR-7,CR-8,CR-10,CR10S,S4,S5 (Pack of 10)

The wheels that are good are perfect, but two of them rolled pretty rough so the QC isnt perfect, but its still a good deal

Several of the rollers have out of round side walls (the part that rides the guide). Doubled checked that the bearings were inserted correctly. The wobbly rollers made it impossible to level my bed. Ended up inspecting and comparing each until I found a straight set to install. 4 of the 10 were not usable. Had a similar issue with an off-brand set but that set had 8 of 10 unusable rollers.

ok for replacement but not an upgrade thats for sure

Why so many packs of 10? Popular Ender series have 13 Bad reviews - obviously not quality

Before buying these I saw the horrid reviews and was quite concerned about buying these. After looking around the only other options were much more expensive than these. So I played it safe and bought more than what I needed. I bought 20 of these and out of all of them I only had 5 that were unusable. The rest were perfectly fine and had good rolling movement and no side to side play. The 5 that were unusable either had side to side play or had rough / crunchy rolling movement. Just buy more than what you need and do the QC work yourself and you will be good to go.

Great

Need some new wheels for my Anycubic Chiron and now it traverse/elevates smoothly! No more sliding prints.

After replacing my throat, heat block, and fan, then tuning my PID, I finally took the plunge and replaced the wheels underneath my bed, all four. All of my prints instantly went from failed to successful. No more divots or blobs, just smooth surfaces. Could not be happier.

Used on a robot arm. Works well

After replacing the wheels on my ender 3 v2, the bed wobbles so i cant even level it properly. 2/3 of the wheels I replaced on the right side arm dont even touch the rail, so all of the weight and pressure is on the bottom wheel. Im quite disappointed with these. Will have to look elsewhere.
