Product Description
A "machine key" isa mechanical component, typically a small piece of metal, used to securely connect a rotating element like a gear or pulley to a shaft, preventing relative rotation between the two parts and ensuring efficient transmission of torque;essentially acting as a locking mechanism to prevent slippage while power is transferred between components in a machine.Machine keys also called shaft keys or key seats - areremovable machine elements installed between shaft key seats and hub keyways to transmit torque in power transmission assemblies. They are also designed to protect a power transmission application by failing first, which protects other component elements
