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)

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.

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.

Great Product

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

They are not even across the diameter. Leads to the bed wobbling

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

Check the spacers. They should be like the ones in this picture. If they are bigger than 8mm diameter or the wrong thickness, they wont work. The wheels I received had the proper spacers and they still roll correctly when tightened down. Five stars.

Works perfect for my CR10s Pro. Only issue I had was 4 of the 10 had bearings with flat spots you could feel when installed. Thankfully I contacted the seller and was sent a new set. The new set had only one bad bearing so if you need all 10 in good working order you will have to wait longer but the new set was sent within one week.

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!

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