Perfect for my drone motors

These bearings are incredibly smooth. I used them to upgrade my racing drone motors and noticed a significant reduction in friction. The P5 grade is noticeable compared to standard ones.

High precision confirmed

I work with small CNC spindles and need reliable components. These bearings run cool even at high speeds. Will definitely order again for future projects.

Good quality, slight delay

The bearings themselves are excellent quality and fit perfectly in my miniature gearbox. Shipping took a day longer than expected, but the product makes up for it.

Solid performance

Very happy with the performance. They handle the load well. I wish the package included a small tube of extra grease, but overall a good purchase.

Great for robotics

Used these in a robotic arm joint. The movement is fluid and there is no play. The packaging was secure and all pieces were intact.

5 FAQ

Q: Do you provide certification for the P5 grade?

A: Yes, we can provide a mill test report upon request for bulk orders. Please contact us directly after purchase.

Q: Is the rubber seal chemical resistant?

A: The 2RS rubber seals offer basic resistance to dust and moisture. For harsh chemical environments, we recommend consulting our technical team.

Q: Are these bearings suitable for 3D printer extruders?

A: Yes, many customers use these miniature bearings for 3D printer extruder assemblies due to their precision and low friction.

Q: Can I mix different bore sizes in one order?

A: Currently, packs are sold per specific size range. However, you can add multiple packs of different sizes to your cart.

Q: What is the temperature range for the pre-lubricated grease?

A: The standard grease supports operating temperatures between -20°C and 120°C. For extreme temperatures, custom lubrication may be required.
