Worm Shaft is a precision CNC-machined core transmission component used for worm gear reduction systems. Adopting integral one-piece structure and precise worm thread processing, it acts as the driving unit to mesh with worm gears, realizing cross-axis power transmission, stable speed reduction and torque amplification. With strict tolerance control on thread profile and concentricity, it provides highly consistent, low-vibration and long-lasting transmission performance for various mechanical deceleration equipment.
