Heavy-Duty Slewing Bearing

1.Product Introduction: Suitable for heavy-duty equipment (such as cranes with a capacity of over 100 tons), with extremely strong load-bearing capacity, capable of bearing axial loads ≥5000kN and anti-overturning moments ≥5000kN·m.
2.Structure Type: It has an integrally forged thick-wall annular shape (wall thickness ≥80mm). The inner and outer rings are made of 42CrMo steel, with built-in three rows of rollers, heavy-duty metal labyrinth seals, and the mounting holes are suitable for high-strength bolts above M30.
3.Size Range: Outer ring diameter: 1500 - 6000mm, inner ring diameter: 1300 - 5500mm, height: 150 - 300mm.
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: Ultra-large port cranes, heavy-duty mining machinery, offshore wind power platforms, large crawler cranes.
6.Key Inspection Items: Flaw detection of forgings (UT/MT inspection), anti-overturning moment, integrity of seals.
