90% of excavator slewing failures are caused by defective slewing ring gears.
Our slewing ring gear strictly controls three core indicators to deliver stable, long-lasting performance for construction machinery.
1. Premium Raw Material
Adopt high-standard bearing steel with 42CrMo grade as base material.
Superior material tensile strength guarantees outstanding anti-fracture performance, with breaking strength reaching 800MPa, effectively avoiding gear cracking under heavy-load working conditions.
2. Integrated Forging & Quenching Process
One-piece integrated forging forming eliminates assembly gaps and weak welding points.
High-frequency integral quenching treatment improves surface hardness and wear resistance, resisting abrasion from long-term frequent rotation and heavy impact.
3. Ultra-High Machining Precision
Precision gear machining ensures tooth pitch error ≤0.05mm.
Uniform tooth clearance reduces vibration, abnormal noise and gear biting wear during excavator rotation, greatly lowering rotating failure rates.
Professional Wear Resistance Verification
All slewing ring gears pass 100,000 times cyclic wear resistance test before delivery.
Stable mechanical properties adapt to harsh working scenarios including mine, construction site, earthmoving and long-hour continuous operation, extending the service life of the whole slewing bearing assembly.
