Smooth Operation
Used these for my RC motor rebuild and they spin incredibly smoothly. No grinding noise at high RPMs.

Perfect Fit
Dimensions were exact according to my calipers. Replaced old worn-out bearings in my machinery without issues.

Good Value
Overall great quality for the price. One was slightly stiff out of the box but loosened up after use.
