Slewing Machine

1.Product Introduction: Integrated mechanical devices containing slewing bearings (such as slewing platforms, slewing drive units), which can be directly integrated into equipment to achieve 360° slewing function.
2.Structure Type: It consists of slewing bearings (ball-type or roller-type), drive motors, gearboxes, and bases. Some are equipped with braking devices, and the bases have standard mounting holes.
3.Size Range: Overall diameter: 500 - 3000mm, height: 100 - 500mm, output torque: 50 - 5000N·m.
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: Slewing platforms of construction machinery, port loading and unloading machinery, rotating platforms of amusement equipment, photovoltaic tracking systems.
6.Key Inspection Items: Slewing accuracy, output torque, braking performance.
