Sleeves with keyways are specialized components commonly used in mechanical systems to facilitate the transmission of rotational motion or torque between shafts and rotating elements. These sleeves feature keyways, which are precisely machined slots or grooves along the bore, allowing them to securely connect to shafts or other components via keys or splines. The keyway ensures proper alignment and prevents slippage during operation, thereby enhancing the efficiency and reliability of the mechanical system.

These sleeves with keyways find widespread application in various industries, including automotive, manufacturing, and machinery. In automotive applications, they are often used in transmissions and drivetrain systems to transmit power from the engine to the wheels efficiently.
