Review on Magneto Bearings Premium Skateboard Longboard by Mario Schultz

One of the toys in the garage uses a bearing of this size in the fan motors. Original replacement engines are very expensive (30 year old German sports touring car) so it's easy to decide to restore the old original engines when the fans start making noise. In this mode, the bearings experience both radial and axial loads, which is not ideal for single row ball bearings. These skateboard wheel bearings should work just fine since the calculated stress is much higher than the stress the fans are putting on them. ABEC 9 quality means they run noticeably smoother and quieter than even brand new bearings. Hopefully that's enough to keep a German skateboard quietly cool over 180 mph.
