Straight key for American Crane 9310

The straight key 402212 serves as a mechanical fastener within the American Crane 9310. It is installed into a machined keyway on both a shaft and its corresponding rotating component, such as a gear, pulley, or coupling. By locking these parts together, the key ensures that torque is transferred effectively from the shaft to the component or vice versa, preventing relative movement during operation.

This component is compatible with the American Crane 9310 model. It is used in various power transmission assemblies throughout the machine, including drive systems, swing mechanisms, and winch assemblies. Proper installation of the key ensures that the shaft and the attached component rotate as a single unit, which is necessary for the consistent operation of the crane's mechanical systems.

In general engineering applications, a straight key acts as a positive drive element. It is designed to withstand torsional loads and prevent slippage between rotating machine parts. By maintaining a fixed alignment between the shaft and the hub, the key allows for the transmission of rotational force while protecting the integrity of the connection under operational stress.
