Reply to "Rear axle diameter and tolerance"

What prevents a bearing from rotating around the shaft is not so much its radial tightening on the shaft but the adhesion between the different bearing faces (inner rings of the bearings, the bearing face of the shaft , spacers, the washer in front of the nut, .....), adhesion depending on the axial force exerted by the nut at the end of the shaft. This is why it is important to tighten this nut to the prescribed torque and prevent it from loosening.
