Double Row Slewing Bearing

1.Product Introduction: Slewing bearings with double-row rolling elements (steel balls or rollers), having strong load-bearing capacity, capable of simultaneously bearing axial, radial loads and overturning moments, suitable for medium and heavy-load equipment.
2.Structure Type: It has an annular shape. The inner and outer rings have double raceways, with two rows of rolling elements (steel balls or rollers) inside, separated by spacer rings to prevent collisions, with seals on both sides, and the mounting holes are suitable for high-strength bolts.
3.Size Range: Outer ring diameter: 500 - 3500mm, inner ring diameter: 450 - 3350mm, height: 30 - 120mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Medium-sized excavators, port cranes, crawler cranes, large amusement equipment.
6.Key Inspection Items: Clearance of double-row rolling elements, anti-overturning moment, integrity of seals.

Product Description

Double Row Slewing Bearings for Heavy-Duty Machinery – Custom-Built for High Load, Impact & Temperature Resistance | Fast Global Delivery

When your equipment faces extreme loads, temperatures, or relentless operational demands, Double Row Slewing Bearings deliver unmatched stability and endurance. Engineered with dual rows of rolling elements, these bearings distribute stress evenly, handling axial, radial, and overturning moments simultaneously. At LUOYANG INNO BEARING CO., LTD, we combine 30+ years of precision manufacturing expertise with agile customization to solve challenges in industries like steel mills, port cranes, and mining excavators. Whether you need a standard or oversized bearing (up to φ5000mm), our solutions are built to thrive where others fail.

Why Do Our Double Row Slewing Bearings Stand Out?

  • Unmatched Load Capacity: Dual-row design supports heavy axial/radial loads (up to 5000kN) and overturning moments.
  • Built for Extremes: Operate reliably in temperatures up to 150℃ or corrosive environments with 42CrMo alloy steel and fluororubber seals.
  • Precision Engineering: Achieve P4-grade accuracy (≤0.01mm runout) for smooth rotation in high-speed machinery.
  • Rapid Customization: Tailor dimensions (outer diameter: 500–3500mm), load ratings, and sealing systems in 30 days.

Where Do Double Row Slewing Bearings Excel?

Application Key Benefits
Steel Mills & Metallurgy Resists molten metal splashes and heavy shock loads.
Port Cranes Absorbs high-impact loads with saltwater corrosion resistance.
Mining Excavators Handles uneven loads with integrated spacer rings.

FAQs

Q: How do your bearings handle 150℃ environments in steel mills?
A: We use ceramic-coated raceways and 42CrMo alloy steel heat-treated for thermal stability.

Q: Can you customize bearings for legacy port cranes?
A: Yes! Share your blueprint, and we'll replicate exact mounting holes, diameters, and seal types.

Q: What material upgrades improve impact resistance in mining?
A: Opt for GCr15SiMn rollers and hardened spacer rings to reduce element collision.

Q: How do you achieve faster lead times for custom sizes?
A: Modular production pre-machines common bearing components, cutting φ3000mm+ delivery to 20 days.
