The term for the lock cylinder component that transfers rotational motion to the bolt works is known as the cam. The cam is a crucial part of the locking mechanism, as it engages with the bolt when the key is turned, allowing for the locking and unlocking action. As the cylinder is rotated by the key, the cam converts this rotational movement into linear motion, which is what physically moves the bolt to either secure or release the door.

Understanding the function of the cam in the context of lock design is essential for anyone studying locksmithing. The cam's role is pivotal since it directly affects the effectiveness and reliability of the locking mechanism. For instance, if the cam were to malfunction or become misaligned, the lock would not operate correctly, leading to potential security vulnerabilities.

Other components such as a lever, spring, and wafer have distinct functions within a lock assembly. The lever typically pertains to disc or lever locks and assists in the locking action rather than transferring motion. The spring provides the necessary tension for the lock's components to return to their original position but does not itself convert motion. The wafer is part of a wafer lock system, aiding in the locking mechanism's complexity instead of providing direct motion transfer.
