Hollow Linear Shaft vs. Solid Shaft: A Complete Guide [Infographic]

Choosing between a Hollow Linear Shaft and a solid shaft depends on the specific requirements of your linear motion system. While both are designed to provide smooth and precise movement, their structural differences affect weight, rigidity, load capacity, and application suitability.

Hollow Linear Shaft

A Hollow Linear Shaft features a central bore, reducing overall weight while maintaining a strong structure. Its lightweight design can lower moving mass and improve acceleration and energy efficiency. The internal space can also accommodate cables, wires, or tubing, making hollow shafts useful for automation, robotics, and compact machinery.

Solid Linear Shaft

A solid shaft has a continuous material structure that provides excellent rigidity and resistance to bending. It is often preferred for applications involving heavy loads, demanding operating conditions, or requirements for maximum structural stability. However, its greater material volume can result in higher weight compared with a hollow design of similar outer diameter.
