Product Description
A parallel machine key, also called a shaft key, is a rectangular metal component used to securely fasten rotating components like gears, pulleys, or couplings to a shaft by fitting into matching keyways on both the shaft and the component, preventing relative rotation between them and allowing torque transmission; essentially, it acts as a mechanical connection to ensure parts rotate together on a shaft without slipping, commonly found in various machinery applications like motors, pumps, and industrial equipment.
