Solid bearings
Good quality steel. They handle radial load well. Just make sure you select the correct size from the list.

Good fit
Fit perfectly into my skateboard wheels. One star off because shipping took a bit longer than expected.

Very smooth operation
No noise at all during operation. The Z shield keeps dust out effectively. Highly recommend for machinery.
