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.

These work perfectly fine for my ender 3 v2. If you know what you are doing and dont overtighten as well as adjusting them right you wont have a issue.

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.

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

They do what there meant to do. Good maintenance upgrade if you print a lot you should have a set on hand as the rubber will wear out on the wheels eventually. Easy to install and makes the machine feel new again.

Some of these may be OK, but after swapping the old wheels on my CR10 bed with these, I noticed a distinct catch in when moving the bed by hand (without the belt connected), and it repeats about every 70mm which is the approximate circumference of these 24mm wheels (where they contact the rails is less than 24mm). I winnowed the batch down to the best and the problem is reduced but it is still present. I have read that can be due to several factors, so I will update this review once I am sure of what the problem is.

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!

I hate to say it but Ive finally found an official product from creality that isnt top quality. When I installed these to replace my worn ones (hadnt used that certain printer for along time and 2 of them got flat sides) and when i installed my first two, then four, then six, they all seemed to be not completely round. They seemed to cause wobbles/binding but luckily number 7 and 8 worked well and its been good ever since. I might recommend the clear ones better but not sure yet. Bought those and will update this is they are a much higher quality than these.
