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

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.

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 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. .

My z axis was getting wobbly on my ender 3 and these fixed the problem.

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.

Great products

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.

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

They turn and keep the belt tight. Thats what they are suppose to do.

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.
