High Load Capacity (5000kN+), Custom Sizes up to φ5000mm, 15-20-Day Delivery
Engineered to withstand extreme loads, harsh environments, and relentless operational demands, Three Row Roller Slewing Bearings are the backbone of heavy machinery in mining, construction, and energy sectors. With a unique triple-row roller design—two radial rows for vertical forces and one axial row for horizontal stability—these bearings deliver unmatched anti-overturning performance. At LUOYANG INNO BEARING, we combine 30+ years of manufacturing expertise with advanced material science to provide solutions that endure temperatures up to 150°C, sudden impacts, and dynamic loads exceeding 5,000 kN.

| Parameter | Specification |

1. Optimized Load Distribution
The triple-row configuration separates axial, radial, and moment loads into dedicated roller paths, reducing stress concentration by 40% compared to single-row designs.
2. Precision Manufacturing
Forged from high-purity 50Mn steel and hardened through carburizing, our bearings achieve a 10x improvement in wear resistance. Components are machined to 0.01mm tolerances using CNC grinders.
3. Modular Flexibility
Three Row Roller Slewing Bearings with split-design options simplify retrofitting into legacy mining excavators or port cranes, cutting installation time by 50%.

Our 3-stage quality control ensures reliability:
1. Material Testing: Spectral analysis and ultrasonic checks for impurities.
2. In-Process Checks: 100% dimensional verification via CMM machines.
3. Final Validation: Load testing at 200% rated capacity and vibration analysis.
| Feature | Us vs. Competitors |
|---|---|
| Lead Time (Custom) | 15–20 days vs. 30–45 days |
| Defect-Free Rate | 99.9% vs. 95% industry average |
| Lifespan | 20,000+ hours MTBF with IoT monitoring |

1. How do your bearings handle 500°C environments?
We use ceramic-coated rollers and high-temperature graphite lubrication, tested in metallurgical kilns.
2. Can you make non-standard sizes like φ5,000mm?
Yes—custom diameters up to 6,000mm are achievable with ±0.05mm precision.
3. What's the fastest delivery time for urgent orders?
Standard bearings ship in 48 hours; custom large units (e.g., φ3,000mm) take 15–20 days.
4. Which materials suit heavy shock loads?
GCr15SiMn rollers with induction hardening endure cyclical impacts in port cranes.
5. Do you assist with legacy equipment retrofits?
Yes—we provide laser alignment and CAD-based remanufacturing services.
