  • Product Description
  • A hollow connecting shaft refers to a shaft component with a hollow internal structure, used to connect two or more parts and transmit torque (rotational force) or motion.
    Its core feature and application advantage lie in its hollow structure:
    1. Reduce weight:
    It is particularly important in weight‑sensitive fields such as automobiles—especially racing and high‑performance vehicles—robots, and sports equipment, as it can reduce rotational inertia, enhance acceleration and deceleration response speeds, and conserve energy.

    2. Internal wiring/piping:
    The hollow inner bore provides valuable channel space.
    It can be used for wiring through wires and cables (such as sensor cables, encoder cables, and power cables), hydraulic lines, pneumatic lines, coolant lines, and more. This results in a cleaner internal device layout and eliminates the risk of external wiring becoming tangled, making it particularly suitable for joints that require 360-degree continuous rotation (such as robot arm joints).
