When pressing a real axle bearing onto the axle shaft, what is the correct area to apply pressure?

The correct area to apply pressure when pressing a real axle bearing onto the axle shaft is the outer race. This is because the bearing is designed to maintain its integrity and alignment when force is applied to the outer race. Pressing on the outer race ensures that the internal components of the bearing, such as the balls or rollers and the inner race, are not damaged or misaligned during installation.

Applying pressure to the inner race can lead to premature bearing failure. This is because the force can cause the rolling elements inside the bearing to be shoved against the inner race, potentially creating a misaligned fit or even damaging the bearing itself. Ensuring that the outer race receives the force allows the inner components to remain free from stress, maintaining the proper function and longevity of the bearing assembly.
