Multiple Choice

A master spline is used to:

A master spline provides the mounting interface on a shaft for attaching a component like a hub, gear, or coupling. It defines the exact size and shape that the mating part must fit onto, ensuring correct alignment and that torque is transmitted properly when the component rotates with the shaft. This is what makes it the best choice: the master spline’s purpose is to secure and locate a part on the shaft, not to measure temperature, lubricate bearings, or directly drive gears.
