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 replaced the wheels on my X gantry when I upgraded my hot end, direct drive mount, and ducting. It took me days of failed prints to figure out that the wheels were a tiny bit out of true, which was hard to detect. The first layers on my prints were wonky, like a loose gantry, and I had an odd spiraling Z- axis deviation. Im mad that something as simple as bad, brand new wheels caused so much frustration. Seems like it is very hard to get quality parts these days.

Worked great on my Ender 3x

The pieces is not centered. All pieces wobbles. I buy to change the ones in the table of my ender 3 pro but is useless cause y cannot even level it because the wobbles in the pieces.

Perfect replacement

I should have listened to other reviews, all of these wheels have poor bearings that cause periodic error on Bed Visualizer. About 2mm from peak to peak, which makes printing impossible because you cannot get a decent first layer even with bilinear mesh turned on. Worthless wheels. Can’t use them.

these are good bearings took out a lot of noise and wobble in the Z axis.

I bought these to replace a damaged wheel on my Ender 3 Y axis but they are so off alignment that the bed moves up and down about a 1mm.

Need some new wheels for my Anycubic Chiron and now it traverse/elevates smoothly! No more sliding prints.

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.
