Which tool is commonly used to install tight-fitting bearings?

The correct answer is a stationary hydraulic press. This tool is specifically designed for applying large amounts of pressure in a controlled manner, which is essential when installing tight-fitting bearings. Bearings need to be installed without damage to their surfaces or misalignment, and a hydraulic press provides the necessary force to push the bearing into position smoothly and evenly.

Using a hydraulic press ensures that the force is applied uniformly, reducing the risk of damaging the bearing or the housing it is being fitted into, unlike other tools that do not provide the same level of control or force distribution. For example, a manual vise might not be able to provide the consistent pressure required, while a hammer and chisel could easily cause damage due to improper force application. A torquing wrench is designed for applying a specific amount of rotational force, typically not relevant for bearing installation. Thus, the stationary hydraulic press is the most appropriate and effective tool for this specific task.
