When removing a bearing from a housing, the correct approach is to apply pressure to the outer ring. This method ensures that the bearing is removed without causing damage to any internal components.

Applying pressure to the outer ring allows for a smooth extraction as it prevents the rolling elements and inner ring from being displaced, which could lead to misalignment or damage. Exerting force on the outer ring also ensures that the inner components remain stable during removal, thus extending their operational lifespan and maintaining the integrity of the bearing.

Other methods, such as applying pressure on the inner ring or directly on the shaft, could lead to improper removal, potential damage to the bearing surfaces, or the risk of damaging the shaft itself. Applying force to the ball bearings is inappropriate, as this could result in deformation or breaking of the rolling elements, leading to further issues with bearing performance. Therefore, the appropriate technique is to exert pressure on the outer ring to facilitate safe and effective removal.
