When removing or installing a bearing, which part should pressure be applied to?

When removing or installing a bearing, pressure should be applied to the inner race. This is because the inner race is designed to fit tightly onto the shaft and allows for the bearing to be supported and maintained in place during operation. When force is applied to the inner race, it ensures that the load is properly transferred through the bearing elements without causing damage to other components.

Applying pressure to the outer race, ball cage, or seal can lead to various forms of damage. The outer race is generally more susceptible to deformation if excessive force is applied, which could compromise the integrity of the bearing. The ball cage is designed to hold the balls in position and not to handle installation or removal forces. Similarly, the seal is a component that protects the bearing from contaminants and retains lubricant, making it unsuitable for bearing installation or removal pressure. Therefore, applying pressure to the inner race is the correct practice to ensure proper bearing service and longevity.
