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)

A lot of reviews show the center ring is off, which people claim makes them unusable. There is a left and right bearing and a brass spacer in the middle. The wheels i got came with every center ring off center, but the ring moves just take a chopstick or something small, and push it to the center very simple, and it lines up the ring. It is a little loose and moves in shipping. I centered them all in 30 seconds. Ill updated once I install and test wheels. Amazing people into tech things cant figure this out.

Ordered spare parts for my ender 3 pro

I have an Ender 3, and I wanted to have some backups of these in case I need them. I havent used any yet, but as they look identical to the stock ones, I cannot see how they can possibly fail.

As the title says, Im not sure if I tighten the wheels too much to the rails but I can see and notice bits and pieces of the wheel falling apart. But overall the wheels perform well as a replacement to my Tronxy-2 wheels which were worn out and making my heat bed wobbly. Now with the new wheels I head bed is no longer wobbly and is very stable. But I have a eerie feeling I may have tighten the screws too tight which might be causing the shavings or pieces of the wheels rubbing off onto the table and head bed. See pictures.

OEM fits perfectly!

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.

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.

Garbage half of these wheels aren’t true centered and the quality control is god awful pieces missing from my wheels as well would not buy again!

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