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)

Had a few come with crushed bearings. The wheels were nice but did not work so well for a smooth print bed. Luckily i had enough to replace the 8 wheels after swapping some bearings around.

Ordered spare parts for my ender 3 pro

I had to replace two of the originals

These wheels worked like new, would recommend these to others.

I should have listened to other reviews, all of these wheels have poor bearings that cause periodic error on Bed Visualizer. About 2mm from peak to peak, which makes printing impossible because you cannot get a decent first layer even with bilinear mesh turned on. Worthless wheels. Can’t use them.

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

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.

I hate to say it but Ive finally found an official product from creality that isnt top quality. When I installed these to replace my worn ones (hadnt used that certain printer for along time and 2 of them got flat sides) and when i installed my first two, then four, then six, they all seemed to be not completely round. They seemed to cause wobbles/binding but luckily number 7 and 8 worked well and its been good ever since. I might recommend the clear ones better but not sure yet. Bought those and will update this is they are a much higher quality than these.

Perfect replacement

I am rather surprised these where wobbly. I purchased as replacements for my Ender 3 bed rollers. After installing the bed ungulate as it traveled along the Y axis! After inspecting all ten rollers I used the four that weren’t terrible.
