Reliable but missing one size
Overall very satisfied with the performance and durability. Unfortunately, my kit was missing the 9mm set, but support resolved it quickly. The rest work great.

Perfect for my RC drone
These bearings are incredibly smooth. I used the 3mm and 5mm sizes for my drone motor upgrades and the difference in noise reduction is noticeable. High quality import.

Good quality but tight fit
The build quality is excellent and they feel very durable. However, the 2mm bearings were a bit tight on my shafts. Might need a slight press fit installation.

Smooth spinning action
Bought these for a custom 3D printer project. The high-speed rating is accurate; they spin freely with very little resistance. Great value for the price.

Great assortment kit
Having all these sizes in one order saved me a lot of time. The packaging was secure and every bearing was individually wrapped to prevent dust.
Q: Can I return the kit if I selected the wrong sizes?
A: Yes, unused items in their original packaging can be returned within 30 days of purchase for a full refund.
Q: What is the load capacity for the 3mm bearing?
A: The dynamic load rating varies by specific model number, but generally supports light to moderate radial loads typical for miniature applications.
Q: What type of grease is used for lubrication?
A: They are pre-lubricated with high-temperature synthetic grease suitable for high-speed applications.
Q: Are these compatible with standard 5mm motor shafts?
A: Yes, we stock a specific model with a 5mm inner diameter that fits standard motor shafts perfectly.
Q: Do these ship from Germany or a local warehouse?
A: While imported from Germany, they ship from our local distribution center for faster delivery times.
