Smooth, Durable Bearings Perfect for 3D Printed Toy Cars
I use these uxcell MR128-2RS deep groove ball bearings in my kids’ 3D printed toy cars, and they work great! The double-sealed design keeps the lubricant inside and dirt out, which means the wheels spin smoothly and last longer — even with rough play. Made from tough chrome steel, these bearings feel sturdy and handle the stress of constant rolling and bumps without wearing out quickly. The size fits perfectly for my projects (8mm inner diameter, 12mm outer diameter), and the noise level is low, so the cars don’t make annoying grinding sounds. Overall, these bearings give my toy cars a professional, smooth rolling feel, and they’re a great value for the price. If you’re building small moving parts or toys, I definitely recommend these!

If you own an AIPER Surfer S1 and the bearing are seized these work great
If you own an AIPER Surfer S1 and the bearing are seized these work great. I have a salt water pool and the bearing seized after 6 months. These fit and work great. AIPER needs a new design.

These fit my Heng Long KV-2 RC tank
Used these bearings for the output shafts of the tank. They fit perfectly into the lower hull and virtually eliminated the considerable slop in these shafts. I expect them to reduce detracking problems with the tank. Would buy again. Definitely worth the money.

Great Bearings!
I know these state they are ABEC 1 spec, but I swear they feel much better than that! I use them in a product I'm working on that I printed on my 3D printer, and have them, in some cases, in relatively small gears (ø~20mm). PLA is very lightweight (so no flywheel effect here), but these small gears spin very nicely with these bearings inserted. I was so impressed with them that I ordered a few more sets. Recommended product.

Exactly what you ordered
I was making a planetary gearbox for a student stem project decided to add alittle more then needed with the addition of bearings. These worked perfect so we’ll I’m making another for my professor. Keep in mind if you make a friction fit and apply to much lateral load when removing them they will break. Small bearing thing sidewall however they were perfect for my specific use case.

Absolute garbage. Inconsistent out of the packaging. Completely failed (locked up) in less than 24h of <60 RPM. You are better off burning your money.

Price is too high for 10pcs.
