The best way to remove a bearing from a shaft is to use a set of pullers with the strain applied to:

Using a set of pullers with the strain applied to the inner race is the correct approach for removing a bearing from a shaft. This method ensures that the force is directly applied to the inner race, which is designed to withstand such stresses.

When the inner race is pulled, it slides off the shaft smoothly, minimizing the risk of damaging the raceway, rolling elements, or the outer race of the bearing. This technique allows for controlled extraction, reducing the potential for misalignment or deformation of the bearing components.

Applying strain to the outer race, while sometimes possible, can lead to issues such as damaging the rolling elements or the cage if the bearing is not properly supported. Similarly, applying force to the shield or the rolling elements can result in deformation, damage, or incomplete removal, complicating the process and potentially leading to the need for bearing replacement. Thus, focusing on the inner race is a best practice in millwright applications for effective and safe bearing removal.
