Perfect for FPV Drone Motors
These micro bearings are exactly what I needed for my custom drone build. They spin incredibly smoothly and handle high RPMs without any noticeable heat buildup. The tolerances seem very tight.

Precise dimensions
Measured several units with calipers, and the inner/outer diameters are spot on. No wobble detected. Will be ordering more for our prototype assembly line.

Great performance for the price
Compared to branded options, these offer 90% of the performance at half the cost. They hold up well under stress. Just make sure to clean them before installation if they sat in storage.

Essential for small motor repairs
I use these daily for repairing small electric motors and dental tools. The consistency across the batch is impressive. The rubber seals keep dust out effectively.

Smooth operation
Used these for a kinetic sculpture project. The silence and smoothness of rotation are outstanding. Highly recommend for any precision mechanical project.

Good quality, fast shipping
Bought the 3mm and 5mm sets for my RC car upgrades. They fit perfectly and reduced the friction significantly. One bearing felt slightly stiffer than the others, but overall a great value.
Q: Are these bearings suitable for underwater applications?
A: While the 2RS rubber-sealed versions offer some protection against moisture, these are not specifically designed for continuous submerged operation. For underwater use, we recommend applying additional corrosion-resistant lubricant.
Q: Can I remove the shields to clean and re-lubricate them?
A: Yes, the ZZ metal shields can be carefully pried off for cleaning and re-lubrication. However, the 2RS rubber seals are generally non-removable without damage. Proceed with caution to avoid bending the shields.
Q: Do you sell these in bulk quantities for manufacturing?
A: Yes, we offer bulk pricing for orders over 100 packs. Please contact our sales department directly through the 'Contact Seller' button for a custom quote.
Q: What is the exact outer diameter for the 5mm inner diameter model?
A: For the standard 5mm inner diameter micro bearing (model 685), the outer diameter is typically 11mm with a width of 5mm. Please check the specific sub-model selection for variations.
Q: What is the maximum temperature these bearings can withstand?
A: Standard grease lubrication allows for operating temperatures up to 120°C (248°F). For higher temperature environments, specialized high-temp grease would be required.
