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

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.

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

Great Product

Worked great on my Ender 3x

These were garbage. Poor quality control. Only 3 out of the 10 were usable. The others were out of round. I knew better but tried them anyway and sure enough my print bed had a wavey motion and was impossible to level.

These wheels are extremely tight - they make it difficult to move the motors

They are exactly what I expected. Havent used them, since they are spares.

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.

Works perfect for my CR10s Pro. Only issue I had was 4 of the 10 had bearings with flat spots you could feel when installed. Thankfully I contacted the seller and was sent a new set. The new set had only one bad bearing so if you need all 10 in good working order you will have to wait longer but the new set was sent within one week.
