The YYQ-500S is a high-precision, universal hard-bearing dynamic balancing machine manufactured in strict accordance with the GB/T 4201-2006 standard. It utilizes a semi-hard bearing structure and an efficient belt-drive system, specifically designed for rotors weighing between 10kg and 500kg. Integrated with a 32-bit industrial control computer and a 15-inch LCD screen, the system provides real-time visualization of unbalance amount, phase angle, and rotating speed. It is highly versatile and particularly suited for plate-type workpieces and center-of-gravity overhung rotors in industries such as paper-making, textiles, and electric motors.





High Precision Performance: Achieves a minimum residual unbalance of $le 0.5$ gmm/kg with an unbalance reduction ratio of $ge 90%$.
Advanced Measuring System: Features independently developed 32-bit measurement software for intuitive operation and high-accuracy data processing.
Durable Construction: The 1800mm lathe bed is crafted from high-quality HT250 cast iron, while the swing frames use QT450 cast iron for superior structural stability.
User-Friendly Interface: Equipped with a 15-inch LCD monitor, LENOVO anti-interference keyboard, and a dedicated vertical industrial control cabinet.
Efficient Belt Drive: Powered by a 4KW motor with an IVNT frequency converter and dedicated filtering for smooth, stable operation.
Versatile Applications: Ideal for balancing a wide range of components including blower fans, agricultural machinery, and various industrial rotors.
