Temperature control is essential when removing bearings because variations in temperature can lead to thermal expansion or contraction of both the bearing and the housing. If the components are not at the appropriate temperature, the bearing may become stuck or misaligned, making it difficult to remove. Proper temperature management helps prevent damage to both the bearing and its housing, ensuring that the components can be safely and effectively removed without risking additional wear or damage.

Effective temperature control may involve methods such as using heating or cooling tools that can carefully manage the temperature of the bearing, allowing it to expand or contract uniformly. This approach minimizes the risk of deforming the bearing or affecting the mating surfaces, which is crucial for maintaining the integrity of these components for future installations.

While the other factors mentioned—cleaning the workspace, using new bearings, and lubricating the bearings—are important in the overall maintenance process, they do not directly address the physical challenges involved in the removal of existing bearings, making temperature control the most critical consideration in this specific context.
