Aokin 3D Printer POM Wheel Plastic Pulley Linear Bearing for Creality Ender 3, Ender 3 Pro, Ender 3 V2, CR-10, CR-10S Series 3D Printer, 10 Pcs

Works as it should

This is the third set of rollers Ive ordered from various Amazon sources and so far, these are the best quality Ive received. All ten rollers look and work perfect. No surface defects on the plastic, no loose fitting bearings, no missing spacers. They worked perfect on my Ender 3 bed and X-carriage. They are well packaged and came with an information sheet. Overall, a very good purchase and Id buy them again.

Great products

Finally pulley wheels that are round! Too many of the other ones Ive tried have been oblong and absolutely ruined my prints. With these, the first 3 I pulled out of the bag and installed were perfect and my printer is resurrected. I havent tried the rest yet, but the last batch I had from another brand were ALL bad. Do recommend.

These are nice wheels. They have the same double 625ZZ shielded bearings as original wheels. I have checked all 10 wheels and all of them have a nice smooth rotation and they are not sloppy. These small bearings can take a surprisingly high load and I will use some of them for my other project.

Came in great shape and was able to swap out a few wheels easily on my Ender 3 V2

I should have payed more for bearings, these things cut corners from the low quality grease to the inconsistent build quality to the sheer amount of friction in these even when warmed up. In the future I hope you can get in contact with your supplier and test the quality of a batch before someone else ends up halfway through a 3d printer rebuild only to find the old worn out bearings roll better than these. Sorry but now both our days are ruined.

Picked up these to replace my Ender 3 wheels that were a year old. Direct replacement with no complaints. Worked as they should.

Perfect fit. All 10 were in good condition with no defects detected. All I did was add a touch of liquid dry lube and they were very smooth. I will buy again if/when needed.

after eating up the stock wheels from bad adjustments I got the clear poly wheels. the clear wheels made a ton of noise and left residue on my rails no matter how i adjusted them so I went back to stock. new wheels and a silent board make my printer damn near a ghost while running now
