Engineered to withstand 500+ ton loads, 150℃ temperatures, and 30+ years of operation. Custom diameters up to φ5000mm with 25 day rapid delivery for non-standard specs.
When your excavator's slewing bearing fails, downtime costs soar. That's why leading OEMs trust LUOYANG INNO BEARING's excavator slewing bearings—precision-engineered to endure harsh mining, construction, and demolition environments. Our bearings combine military-grade materials with modular designs, ensuring seamless rotation under extreme axial/radial forces.

30+ Years of Heavy-Duty Expertise
We specialize in heavy-duty slewing bearings for excavators (6-50 tons), leveraging three decades of R&D to optimize load distribution and fatigue resistance. Our vertical integration—from steel forging to heat treatment—guarantees consistent quality.

1. Share Requirements: Send excavator model, load data, and environmental conditions.
2. Simulate & Optimize: Our engineers run FEM/ANSYS simulations to validate bearing performance.
3. Test Rigorously: Prototypes undergo 12+ stress tests (fatigue, vibration, thermal cycling).
4. Produce & Deliver: Bulk orders ship in 15-30 days with pre-assembly inspection reports.
Every excavator slewing bearing undergoes:
✅ Ultrasonic flaw detection
✅ Torque tolerance testing (±5%)
✅ 72-hour salt spray corrosion resistance check
✅ Dimensional accuracy verification (ISO 492 Class 5+)
Warranty: 5-year structural integrity guarantee.

1. How do your bearings handle compact excavator designs?
We use 3D scanning to retrofit older models, optimizing gear meshing and load paths without blueprints.
2. What materials resist abrasive mining debris?
42CrMo steel with induction-hardened raceways (60 HRC) + fluorocarbon seals.
3. Can φ5000mm bearings handle 50,000 N·m loads?
Yes—double-row roller designs distribute stress evenly, validated via ANSYS simulations.
4. How do you achieve fast lead times?
Modular production with pre-forged components cuts machining time by 40%.
5. Do you support marine environments?
Stocked bearings include zinc-nickel coatings for saltwater corrosion resistance.
