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)

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.

They are not even across the diameter. Leads to the bed wobbling

OEM fits perfectly!

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

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

Item does as explained in the description..

I used these as replacements on my creality cr-10. Everything worked great.

They do what there meant to do. Good maintenance upgrade if you print a lot you should have a set on hand as the rubber will wear out on the wheels eventually. Easy to install and makes the machine feel new again.

I was able to get enough working wheels out of this set to do what I wanted, but you can grab the center bearings and slide the plastic roller back and forth a bit. I dont think the shims between the rollers are precisely the same width as the shoulder inside of the roller, and that mismatch allows for some slop. Its a great value for the price, but test the ones that youre planning to use before you screw them in.
