A ball or roller bearing has an interference fit with the housing in which it is being installed with a hydraulic or arbor press. Upon what surface should the sleeve of the press be applied?

Athe shaft
Bthe housing
Cthe inner race
Dthe outer race
AI Explanation

The correct answer is D) the outer race. When installing a ball or roller bearing with an interference fit into a housing, the press sleeve should be applied to the outer race of the bearing. This is because the outer race is the surface that needs to be pressed into the housing. Applying the force to the outer race ensures that the bearing is properly seated and aligned within the housing. The other options are incorrect because applying force to the shaft, the housing, or the inner race would not properly install the bearing. The shaft and inner race are not the surfaces that need to be pressed into the housing, and applying force to the housing itself could potentially damage the housing.
