Advantages of Double Ball Rubber Joints

1. Superior Displacement Compensation

Three-dimensional compensation: axial ±15 mm + lateral ±10 mm + angular ±5° (under DN100 conditions)

Comparative Advantage: 40% improvement in compensation capacity compared to single-ball joints, no additional hinge brackets required

2. Excellent Vibration Damping and Noise Reduction

Vibration transmission rate ≤5% (tested data, single-ball joints approximately 15%)

Case Study: Noise levels in a power plant's pump room reduced from 95 dB to 75 dB

3. Long-Term Fatigue Resistance

Dynamic Lifespan: ≥5,000 full displacement cycles (GB/T 26121 standard)

Enhanced Design: Double-layer steel wire skeleton
