2025-12-29

Core Advantages and Working Principles of Hollow Shafts A hollow shaft is a shaft component with a hollow structure used in mechanical design. It realizes power transmission through a central through-hole combined with internal and external keyways, and its outer surface is often processed into a stepped cylinder to adapt to different installation requirements. Compared with solid shafts, hollow shafts have significant weight advantages, while also exhibiting outstanding performance in torsional resistance and material utilization. According to the principles of material mechanics, when the shaft body bears torque, the outer edge bears the main torque, and the utilization rate of the internal area is low.
