uxcell MR148-2RS Deep Groove Ball Bearings 8mm Inner Dia 14mm OD 4mm Bore Double Sealed Chrome Steel Blue Seal Z2 10pcs

Nice! Good size ratio for hobby. Smooth operation.

Everything worked as it should .. quick arrival ..

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.

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.

Good bearings at a good price, the quality seems good

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!

Buenas rolienras, quedan perfectas con mi herramienta

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.
