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 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 were garbage. Poor quality control. Only 3 out of the 10 were usable. The others were out of round. I knew better but tried them anyway and sure enough my print bed had a wavey motion and was impossible to level.

Several of the rollers have out of round side walls (the part that rides the guide). Doubled checked that the bearings were inserted correctly. The wobbly rollers made it impossible to level my bed. Ended up inspecting and comparing each until I found a straight set to install. 4 of the 10 were not usable. Had a similar issue with an off-brand set but that set had 8 of 10 unusable rollers.

Ordered spare parts for my ender 3 pro

I bought these to replace bad bearings on my 4 year old ender 3. And they work great. Theyre east to install and they are extremely durable theyve been running great

After replacing the wheels on my ender 3 v2, the bed wobbles so i cant even level it properly. 2/3 of the wheels I replaced on the right side arm dont even touch the rail, so all of the weight and pressure is on the bottom wheel. Im quite disappointed with these. Will have to look elsewhere.

wheels cause bed to wobble up and down

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

These wheels worked like new, would recommend these to others.

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.
