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)

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

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.

Used on a robot arm. Works well

OEM fits perfectly!

6 out of 20 wheels that Ive ordered are completely not usable, the inner washer is displaced and blocking the bearings hole.

Thinking that the clear wheels would be better I was so wrong, they where too loud. I bought these hoping for origanal and thats what I got. Perfect space size no binding just smoooooth

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.

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.

wheels cause bed to wobble up and down
