Fast delivery
Arrived quickly and well packaged. No rust or damage. I use these for small electric motors and they perform reliably.

Good value
Solid bearings for general machinery use. One pack had a slightly tighter fit than the others, but nothing major. Overall satisfied.

Smooth rotation
Bought the 625Z for a drone motor repair. They spin very freely and seem well lubricated from the factory. Great quality for the price.

Perfect for my RC car
These bearings fit perfectly in my 1/10 scale buggy. The rotation is smooth and free of any grinding noise. Highly recommend for hobbyists.

Exactly as described
The dimensions match the standard specs perfectly. I ordered the 628Z and it fit my spindle without any modification needed.
