High-Performance Slewing Machines for Heavy-Duty Applications | Custom Solutions & 48H Fast Delivery

When your equipment faces extreme loads, high temperatures, or non-stop operational demands, every component matters. At LUOYANG INNO BEARING CO., LTD, we engineer slewing machines that redefine durability and precision. Designed for metallurgical, port, and construction machinery, our solutions handle axial loads up to 12,000 kN and operate seamlessly in environments reaching 150°C. With 30+ years of expertise, we deliver not just bearings – but 360° rotational systems built to outlast your toughest challenges.

Core Technical Specifications

• Slewing Diameter: 500mm – 5000mm (customizable up to φ5000mm)
• Axial/Radial Load Capacity: 1,500 kN – 12,000 kN
• Precision Grade: ISO P5/P6 (radial runout ≤0.05mm)
• Material: 50Mn/42CrMo steel, heat-treated to 58-62 HRC hardness
• Operating Temperature: -30°C to +150°C
• Noise Level: <35dB at 2,000 RPM

Where Our Slewing Machines Excel?

Heavy-Duty Industrial Applications

1. Metallurgy: Continuous casting turntables, ladle cranes

2. Port Machinery: Container cranes, ship loaders

3. Renewable Energy: Solar tracker systems, wind turbine yaw drives

4. Construction: Excavator swing systems, drilling rigs

Our rotational drive units are proven in environments where dust, shock loads, and thermal stress cripple standard bearings. For example, a φ3000mm slewing machine in a steel mill's converter tilting mechanism has operated flawlessly for 55,000+ hours – 22% longer than previous suppliers' solutions.

Customization Made Simple

4-Step Process for Tailored Solutions

1. Requirement Analysis: Share your load charts, speed, and environmental factors (dust, temperature, corrosion).

2. Prototyping: Receive 3D models and FEM stress reports within 72 hours.

3. Production: Track real-time progress via modular manufacturing.

4. Validation: Full-load testing with detailed performance reports.

Quality Assurance You Can Trust

Triple-Layer Inspection System

1. Material Testing: Ultrasonic checks for steel integrity.

2. Process Control: Dimensional accuracy within ±0.01mm post-heat-treatment.

3. Final Validation: 30+ parameters tested, including:

• 500-hour lifespan simulation
• Hydraulic pulsation tests (5 million cycles)
• Impact resistance up to 150 kN

All slewing rings come with a 18-month performance warranty.

Global Delivery Network

• Standard Units: 1,000+ in stock – shipped worldwide in 3-5 days.
• Custom Orders: 15-25 days production (50% faster than industry average).

Urgent requirement? Our dual-track system prioritizes emergency orders without compromising quality.

Lifetime Support Commitment

• Pre-Installation: Free CAD/3D model integration for your machinery.
• Post-Installation: IoT-driven wear monitoring with real-time alerts.
• Legacy Retrofitting: Adapt non-standard systems to modern slewing drives.

FAQ

Q: What's the minimum order quantity for custom products?

A: We accept single-unit orders with full prototyping support.

Q: How do you ensure precision in high-load conditions?

A: P4-grade grinding and 100% post-assembly noise/vibration tests.

Q: Can you retrofit old port cranes?

A: Yes – 83% of our custom projects involve legacy machinery upgrades.
