In industries such as mining, construction materials, and chemicals, vibrating screens are core equipment for material grading and screening, with their performance directly impacting production efficiency and product quality. As the “power heart” of vibrating screens, the reliability of vibrators and drive systems is critical.

The ZDQ series of high-efficiency vibrators and drive systems, by adopting FAG dedicated vibration bearings and sealing technology, deliver comprehensive advantages including powerful excitation force, stable operation, and extended service life, making them a preferred solution in industrial screening. Below, we analyze their core competitiveness from three aspects: technical design, performance advantages, and long-term value.

I. ZDQ Vibrator: FAG Dedicated Bearings Enable High-Performance Excitation

The vibrator, as the power source of a vibrating screen, must operate stably under high-frequency vibrations, strong impacts, and complex loads. The ZDQ series utilizes FAG dedicated vibration screen bearings, achieving significant performance improvements through targeted design:

1. High-Strength Materials and Advanced ManufacturingFAG bearings are made of high-purity carburizing steel, treated with specialized heat processes to achieve surface hardness exceeding 60HRC while maintaining a tough core. This enhances fatigue resistance by 40%. Combined with precision raceway grinding technology, friction losses are minimized, extending bearing service life under high-frequency vibrations.
2. Dynamic Load Optimization DesignTo address the rotational characteristics of eccentric blocks in vibrating screens, FAG bearings employ asymmetric roller profile modification technology, optimizing contact stress distribution and preventing localized overloads. Customized clearance matching accommodates dynamic deformation of the vibrator shaft, ensuring stable excitation force output with amplitude fluctuations ≤5%.
3. Noise Reduction and Thermal ManagementFilled with FAG high-temperature grease and paired with precision sealing, direct metal-to-metal friction is reduced, achieving operating noise levels below 75dB (20% lower than conventional bearings). Optimized raceway heat dissipation design maintains operating temperatures below 70°C, preventing lubrication failure caused by overheating.

II. Drive System: FAG Bearings + Sealing Technology Safeguard Power Transmission

The drive system employs FAG bearings and seals.

Vibrating screen drive systems require efficient power transmission under continuous high torque while resisting harsh environmental factors like dust and moisture. The ZDQ drive system integrates FAG bearings and sealing solutions, delivering multiple technological breakthroughs:

1. High-Load Bearing ConfigurationThe drive end employs FAG spherical roller bearings, whose double-row roller structure simultaneously withstands combined radial and axial loads, increasing load capacity by 30% compared to standard bearings. A unique spherical outer ring design automatically compensates for shaft misalignment, preventing abnormal wear caused by installation errors.
2. Multi-Stage Sealing ProtectionThe sealing system combines “labyrinth seals + contact lip seals”:
3. Precise Preload ControlAxial clearance is adjusted via preload springs or shims, eliminating drive system backlash. This ensures gear meshing accuracy, achieving 98% power transmission efficiency and preventing energy loss from slippage.

III. Full Lifecycle Value: Balancing Efficiency and Cost Savings

The ZDQ vibrating screen solution with FAG bearings delivers significant advantages across short-term efficiency and long-term operations:

• 15% Increase in Excitation Force: Enhanced screening efficiency boosts throughput and shortens production cycles.
• 60% Reduction in Failure Rate: Average bearing lifespan exceeds 20,000 hours, minimizing unplanned downtime losses.
• 10% Energy Savings: Low-friction design and precise transmission reduce motor load, saving tens of thousands in annual electricity costs.
• Simplified Maintenance: Modular bearing units enable rapid replacement, cutting downtime for repairs by 70%.

In the Industry 4.0 era, equipment reliability has become a cornerstone of corporate competitiveness. The ZDQ series of vibrating screens, by integrating FAG dedicated bearing technology, redefines screening efficiency benchmarks with “high excitation force, low failure rates, and extended lifespan.”

Whether for new production line planning or retrofitting older equipment, adopting FAG bearing-driven vibrating screen solutions ensures synchronized improvements in productivity and economic benefits, empowering enterprises to seize opportunities in competitive markets.
