Excellent Precision
These bearings are incredibly smooth and fit perfectly in my custom build. The P5 grade is noticeable compared to standard ones.

Fast Spin
Low friction confirmed. Used them for a high-speed spindle project and they handle the RPM well.

Perfect for Drones
Upgraded my quadcopter motors with these. Spin time increased and vibration decreased significantly. Highly recommend.

Good Value
Quality is high but price is a bit steep compared to generic brands. You get what you pay for though.

Genuine Japanese Quality
Noticeable difference in build quality. No play whatsoever and the shields are secure. Will buy again.
Q: Are these stainless steel?
A: No, these are made from Chrome Steel GCr15 for maximum durability and load capacity. They are pre-greased to prevent rust.
Q: Which bearing fits a 6mm shaft?
A: The 606 model is designed for a 6mm inner diameter shaft. Please select the 606 option from the variant menu.
Q: Do you sell compatible lubricant?
A: Yes, we carry high-speed bearing grease in our accessories section that is compatible with these MBA bearings.
Q: Can I remove the metal shields?
A: While possible, removing the ZZ shields is not recommended as it exposes the internals to debris and voids the lubrication seal.
Q: What is the difference between P4 and P5?
A: P4 offers higher precision and tighter tolerances than P5. Choose P4 for high-speed or precision instrumentation applications.
