Review: 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!
Review: 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.
