I'm used to tightening the axle nut so that slight drag is produced from the bearings and then backed off slightly. U-01210A-1 is long enough to preclude getting any drag on bearings at all and virtually no compression on the wave washers. Can that be right?
The type of plain bearing that is in the wheel is not meant to have any axial load, so the axle bolt shouldn't ever be tight enough to induce a change in friction that you can feel.
If everything is as intended, the wavy washers should be compressed just enough to induce some friction on the inner race of the bearing so that it doesn't rotate on the shaft.
