Perfect for my drone build
These bearings are incredibly smooth. I used the MF85 size for my motor mounts and there is virtually no friction. Genuine Japan import quality is noticeable compared to generic brands.

Quiet operation
Very quiet during operation. I replaced the bearings in my cooling fan assembly and the noise level dropped significantly. The flange helps with alignment too.

Genuine BJK quality
I have been using BJK bearings for years in my RC cars. These flanged models stay in place nicely without needing extra retainers. Highly recommended for high RPM applications.

Value for money
Good value for a 10-pack. One bearing had a tiny bit of resistance initially but smoothed out after a few minutes of use. Overall satisfied with the purchase.

Good quality, slight shipping delay
The bearings themselves are excellent quality and fit perfectly into my 3D printer idler pulleys. Took a bit longer to arrive than expected, but the product is worth the wait.
Q: Do I need to add more grease before installation?
A: No, the bearings come pre-lubricated with standard grease suitable for most general applications. Additional lubrication is not necessary unless used in extreme conditions.
Q: Is there a bulk discount for larger orders?
A: Yes, we offer tiered pricing for bulk purchases. Please contact our sales team directly through the store interface for a quote on orders over 50 packs.
Q: Can these handle high-speed applications?
A: Yes, these miniature bearings are designed for high RPMs, commonly used in drones and RC motors up to 30,000 RPM depending on lubrication.
Q: Are these bearings made of stainless steel?
A: No, these are made of Chrome Steel GCr15 for optimal hardness and durability. They are coated to prevent rust under normal conditions.
Q: What are the dimensions for the MF63 model?
A: The MF63 model has a bore of 3mm, an outer diameter of 6mm, and a width of 2.5mm including the flange.
