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)

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.

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.

Perfect replacement

Used on a robot arm. Works well

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.

When I replaced my stock wheels, it worked great for ~100 hours. A couple wheels had flat spots, once those were sorted out the rest worked great. They were not overly tight, but now have grooves and cant be tightened enough to prevent wobble on the y axis.

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.
