Good quality, tight fit

Quality seems high for the price. The 5mm ID was a very tight fit on my shaft, required a gentle press. Once installed, they run quietly.

Consistent dimensions

I ordered a mix of sizes for a robotics project. Caliper measurements matched the specifications exactly. Will order again.

Perfect for my drone build

These bearings fit perfectly on the motor shafts. Very smooth rotation and no noticeable play. The flange helps keep them secured in the housing.

Great value bulk pack

Buying in bulk saved me money. All bearings were individually wrapped and free of rust. Excellent for spare parts inventory.

Smooth operation

Replaced old bearings in my 3D printer fan assembly. The noise level dropped significantly. Very happy with the performance.
