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)

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.

I replaced the wheels on my X gantry when I upgraded my hot end, direct drive mount, and ducting. It took me days of failed prints to figure out that the wheels were a tiny bit out of true, which was hard to detect. The first layers on my prints were wonky, like a loose gantry, and I had an odd spiraling Z- axis deviation. Im mad that something as simple as bad, brand new wheels caused so much frustration. Seems like it is very hard to get quality parts these days.

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.

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

Ordered spare parts for my ender 3 pro

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

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

Has to replace a few old wheels that kept locking up on my ender 3 and these worked perfect

The pieces is not centered. All pieces wobbles. I buy to change the ones in the table of my ender 3 pro but is useless cause y cannot even level it because the wobbles in the pieces.

Half of the wheels had tiny nicks which feel like a flat spot in the wheel (which is the issue I was trying to fix when I bought them). They are all thrown into one bag. Wish they were packed better because from my experience if you don’t want any banding these wheels have to be absolutely flawless. Wish somebody made a better version. Would gladly pay more for higher quality wheels.
