Good quality, minor packaging issue
The bearings themselves are excellent quality and spin freely. One package arrived slightly crushed, but the parts were intact.

One defective unit
Most of the bearings were great, but one had a rough spot when spinning. The rest work fine so I kept the set.

Perfect for my drone build
These bearings fit perfectly on the 2mm shaft. Very smooth rotation and the retaining ring holds securely. Great for high RPM motors.

Smooth operation
Low friction and very quiet. I used these for a robotics project and they performed flawlessly under load.

Exact specs
Measured with calipers and the dimensions are accurate. The flange thickness is standard which made mounting easy.
Q: What is the recommended shaft tolerance?
A: For optimal performance, we recommend a shaft tolerance of h5 or h6 for the 2mm inner diameter.
Q: Are these bearings corrosion resistant?
A: These are made of Chrome Steel. For high corrosion resistance, we recommend our Stainless Steel series.
Q: What type of grease is used for lubrication?
A: They are pre-greased with standard lithium-based grease suitable for general mechanical applications.
Q: Is the retaining ring pre-installed or separate?
A: The retaining ring is included in the package and is designed to be installed separately onto the shaft.
Q: Can these handle axial loads?
A: Flanged bearings can handle limited axial loads due to the flange, but they are primarily designed for radial loads.
