Slewing Ring Bearing

1.Product Introduction: General-purpose slewing bearings, divided into ball-type and roller-type, can enable the equipment to rotate 360° and bear compound loads, are suitable for multiple industries, and different seals and precisions can be selected.
2.Structure Type: It consists of a fixed ring + a rotating ring + rolling elements + cages + seals. The rolling elements are divided into single-row or double-row according to the load. The cages prevent collisions, and the seals protect the raceways.
3.Size Range: Outer ring diameter: 100 - 4000mm, inner ring diameter: 80 - 3800mm, height: 8 - 150mm.
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: Construction machinery, wind power, machine tools, amusement equipment, port machinery.
6.Key Inspection Items: Dimensional accuracy, slewing flexibility, running noise of rolling elements.
