Keystock

Key stock, also known as keystock or key bar, is a type of fastener used to transmit torque between a shaft and a rotating component, such as a pulley, gear, or sprocket. It is typically a rectangular, bar-shaped piece of metal that is inserted into a matching keyway or keyseat in both the shaft and the component to prevent relative motion between them. Key stock serves several important purposes in mechanical systems: Torque Transmission: It ensures that when the shaft rotates, the component connected to it also rotates, effectively transmitting torque. Anti-Slippage: By fitting precisely into the keyway, key stock prevents the component from slipping or rotating independently of the shaft. Alignment: It aids in the proper alignment of components, ensuring that they are correctly positioned and synchronized. Key stock is available in various materials, including carbon steel, stainless steel, and brass, to suit different applications and environmental conditions. It comes in standardized sizes, such as square or rectangular profiles, to fit into corresponding keyways. Overall, key stock is a critical component in machinery and equipment where precise torque transmission and alignment are essential for proper operation.
