When pressing a bearing into the housing, you should press against what?

When pressing a bearing into the housing, it is essential to apply pressure to the outer race of the bearing. This is because pressing against the outer race ensures that the bearing is correctly seated within its housing without causing damage to the internal components. If pressure is applied to the inner race or the cage of the bearing, it can result in the rollers or balls within the bearing being misaligned or damaged.

Using the outer race allows for an even distribution of force, maintaining the integrity of the bearing’s internal structure and ensuring optimal performance. Furthermore, applying pressure directly to the shaft can lead to similar issues and does not provide the necessary control needed for accurate installation. Thus, pressing against the outer race is the proper method when installing a bearing into a housing.
