Large Diameter Slewing Ring

Large diameter slewing bearing (Large Diameter Slewing Ring) as the core of heavy machinery rotary joints, in the market is positioned as a high-load, high-reliability precision transmission scheme. Its basic structure consists of an inner ring, an outer ring, rolling elements (balls or rollers) and an integrated sealing system, which can withstand huge axial forces, radial forces and overturning moments at the same time. The core technical advantage of the product lies in its “shaftless” design. The integrated gear structure simplifies the drive system of the whole machine. While ensuring 360-degree smooth rotation, it significantly improves the structural rigidity and operating accuracy of the equipment. It is an indispensable power hub for large-scale lifting, mining and energy equipment. This series of products usually use 42CrMo or 50Mn and other high-strength alloy steel forgings, the raceway after induction hardening treatment, the hardness can reach HRC 55-62, to ensure the fatigue life under extreme conditions. The technical specifications cover a large diameter range from 1000mm to more than 5000mm, supporting internal teeth, external teeth or toothless configurations. Its design advantages are reflected in the highly integrated installation hole position and multi-layer lip seal, which greatly optimizes the field installation efficiency and reduces the maintenance frequency. Whether it is an offshore operation platform with high salt spray or a dust-intensive mining site, large-diameter slewing bearings can bring long-term economic benefits to customers by virtue of excellent material toughness and environmental adaptability.
