The YYQ-200S is a high-precision, universal hard-bearing dynamic balancing machine manufactured strictly according to GB/T 4201-2006 standards. Utilizing a semi-hard bearing structure and an efficient belt-drive system, it is designed for rotors weighing between 2kg and 200kg. The system integrates a 32-bit industrial control computer and a 19-inch LCD screen to provide real-time data on unbalance amount, phase angle, and rotating speed. It is highly versatile, making it the preferred choice for balancing plate-type workpieces and overhung rotors in the paper-making, textile, and agricultural industries.





High Precision: Achieves a minimum residual unbalance of $le 0.5$ gmm/kg with an unbalance reduction ratio of ≥90%
Advanced Control: Features independently developed 32-bit measurement software for intuitive, high-accuracy data processing.
Robust Construction: The 1200mm lathe bed is made of high-quality HT250 cast iron, while swing frames utilize QT450 cast iron for maximum stability.
User-Friendly Interface: Equipped with a 19-inch LCD screen, LENOVO anti-interference keyboard, and a dedicated industrial control cabinet.
Flexible Applications: Specially suited for plate workpieces and center-of-gravity overhung rotors in motors, fans, and agricultural machinery.
Reliable Components: Includes domestic famous brand low-voltage components and an IVNT frequency converter with dedicated filtering for stable operation.
