Good quality, slight packaging issue
The bearings themselves are top notch. One of the bags was slightly torn upon arrival but the bearings were unaffected. Great value for the precision.

Exact specifications met
Measured with calipers and the dimensions are spot on. The side shields keep dust out effectively. Will purchase again for future projects.

Bulk buy satisfied
Bought multiple sizes for inventory. Consistency across all sizes is impressive. Low noise operation even under load.

Perfect for my drone build
These bearings spin incredibly smoothly. I used the 3mm inner diameter for my motor shafts and there was zero wiggle. Genuine Japan import quality is noticeable.

High speed performance
Running at high RPMs without overheating. The flanged design makes installation much easier than standard bearings. Highly recommend for competitive racing.
Q: Can I clean and re-lubricate these?
A: Yes, you can remove the shields carefully to clean and re-grease, but this may affect the precision and warranty.
Q: What is the maximum RPM for the 5mm bearing?
A: Depending on load, these can handle up to 30,000 RPM comfortably due to the high precision rating.
Q: Is the grease food grade?
A: No, this is standard industrial lubrication suitable for mechanical applications only.
Q: What is the difference between F and MF series?
A: F series typically refers to standard flange dimensions, while MF may indicate specific metric flange variations. Check the datasheet for exact outer flange diameter.
Q: Are these suitable for water exposure?
A: While they have side shields, they are not fully sealed against water. We recommend avoiding direct submersion.
