Roller Bearing Slewing Ring

1.Product Introduction: Slewing rings with rollers as the rolling elements, having stronger load-bearing capacity than those with balls, impact-resistant, suitable for slewing equipment under heavy loads and harsh working conditions.
2.Structure Type: It has a thick-wall annular shape. The inner and outer rings have double raceways, with built-in single-row or multi-row cylindrical or tapered rollers, steel cages, heavy-duty seals, and the mounting holes have anti-loosening designs.
3.Size Range: Outer ring diameter: 500 - 3000mm, inner ring diameter: 450 - 2850mm, height: 25 - 100mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Port cranes, metallurgical equipment, large wind power main units, heavy-duty mining machinery.
6.Key Inspection Items: Roller assembly clearance, anti-overturning moment, dust-proof performance of seals.

Product Description

High-Performance Roller Bearing Slewing Rings for Heavy Industrial Machinery

Engineered for Extreme Loads, Precision, and Longevity in Metallurgy, Mining, and Port Equipment

When your machinery faces relentless heavy loads, abrasive dust, or scorching temperatures, a roller bearing slewing ring isn't just a component—it's your operational lifeline. At LUOYANG INNO BEARING CO., LTD, we've spent 30+ years perfecting slewing rings that outlast industry standards, combining unmatched load capacity (up to 15,000kN axial) with precision engineering for industries where downtime isn't an option.

Optimized Solutions for Critical Industrial Scenarios

  • Metallurgy: Surviving the furnace with low-deformation alloy steel and carburized slewing ring raceways.
  • Port Machinery: Defying impacts with hardened rollers and shock-absorbing raceway geometry.
  • Mining: Conquering corrosion with zinc-nickel coatings and multi-labyrinth seals to cut premature failures.

Rigorous Processes for Reliable Performance

Manufacturing Excellence:
Forging ultra-dense alloy steel, surface hardness ≥60 HRC through carburizing/nitriding, and raceway roughness ≤0.4μm Ra.

Quality Assurance:
100% raw material spectrometry, 3D coordinate inspection (±0.005mm accuracy), and 12+ performance tests including vibration, noise, and lifespan.
