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

My printers original wheels had developed flat spots from having the eccentric nuts over-tightened, and were seriously messing up layer height consistency and positioning accuracy. These replacements were an exact fit and immediately fixed my problem. I just used 6 for the Z axis and kept 4 as spares.

I had a bad set of wheels on a Ender 3 Pro heat bed and replaced them with these wheels. The bed is much smoother now and the prints come out well. The original wheels from Creality were loose from the start even after tightening the bolts. These are more stable. They seem good quality. I guess time will tell how well they hold up but for now they are good. .

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

Use these for 3D printer and laser biulds works great

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.

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.

Took me a while to figure out why my first layers came out wavy looking and uneven. Changed out the wheels and now Im printing flat again. Good quality and good value.

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.
