Internal Gear Slewing Bearing

Internal Gear Slewing Bearings: Engineered for Extreme Performance

When precision meets durability, Internal Gear Slewing Bearings deliver unmatched reliability in heavy machinery. Designed for applications where space constraints and harsh conditions collide, these bearings feature gears integrated into the inner ring, optimizing torque transmission while protecting components from dust, debris, and extreme temperatures up to 150°C. At LUOYANG INNO BEARING CO., LTD, our three decades of expertise ensure your equipment operates smoothly under axial loads up to 50,000 kN and radial forces exceeding 150,000 kN·m.

Why Choose Us?

1. Built to Withstand Industrial Demands

• High-Temperature Resilience: Specialized alloys and ceramic coatings maintain structural integrity even in continuous casting machinery exposed to 500°C+ environments.

• Heavy-Load Superiority: Reinforced gear teeth and triple heat-treated raceways handle shock loads common in blast furnaces and rolling mills.

• Space-Saving Design: Internal gears minimize footprint by 15-20% compared to external gear models, ideal for compact crane slewing mechanisms.

2. Precision You Can Trust

Every product undergoes:

• P4-Grade Grinding: Achieves ±0.005mm radial runout for seamless alignment in multi-stage systems.
• AGMA 10-12 Gear Accuracy: Hardened tooth surfaces (HRC 58-62) reduce backlash to ≤0.05mm, ensuring smooth rotation in ladle turrets.
