Lightweight: Because the center section is hollow, hollow splined shafts are lighter than solid shafts, which is useful in applications where weight reduction is required to increase efficiency or reduce load.
Stiffness: Despite being hollow, the splined shaft is designed to provide sufficient stiffness to withstand torque and prevent bending.
Transmitting Power: Spline grooves allow mating with keys to transmit power to other mechanical components, such as gears or couplings.
Space Savings: In some designs, hollow splined shafts can be used to transport oil, gas, or other media through the interior of the shaft, saving space and reducing complexity.

Hollow spline shafts are widely used in various machinery and equipment, especially where light weight, high stiffness and the ability to transmit power are required.
