The component that rotates and provides a bearing surface in a lock is the Wheel Post. In many locking mechanisms, particularly combination locks, the Wheel Post is crucial as it allows other components to rotate around it, facilitating the locking and unlocking process. Its design provides the necessary support and stability for the wheels to function properly while ensuring that they can turn smoothly.

The Wheel Post serves as a pivotal component that integrates with other parts of the lock, affecting how the locking mechanism operates when the correct combination is input. This capability to rotate and provide a stable bearing surface differentiates it from the other components listed, which serve different roles in the locking mechanism. The other options, like the Wheel Pack and Fly, do not specifically describe a bearing surface or a rotating component in the same way.
