The YYQ-100S is a universal hard-bearing dynamic balancing machine engineered for high-precision balancing of various rotors. It features a belt-drive system and a specialized 32-bit industrial control computer for data processing. With a 19-inch LCD screen displaying unbalance amount, phase angle, and real-time speed, it is widely used in industries such as electric motors, blowers, textile machinery, and agricultural equipment. It is suitable for both single-side and double-side balancing of disk-shaped and overhanging rotors.





High Precision: Advanced 32-bit industrial control system ensures pinpoint accuracy in measuring unbalance and phase angles.
Durable Construction: Built with HT250 cast iron lathe bed and QT450 swing frames for maximum stability and reduced vibration interference.
Easy Operation: Equipped with a 19-inch LCD monitor and an intuitive, Windows-style software interface for real-time monitoring.
Versatile Application: Ideal for a wide range of workpieces, including motor armatures, fan impellers, paper machinery rollers, and more.
Safe & Reliable: Features lockable and adjustable clamp safety frames and piezoelectric sensors for secure and consistent testing.
Stable Drive System: The belt drive (1.5kw motor) ensures smooth rotation and minimizes errors compared to direct drive systems for specific rotors.
